  • AT91SAM7X512's SPI peripheral gets disabled on write to SPI_TDR

    - by Dor
    My AT91SAM7X512's SPI peripheral gets disabled on the X time (X varies) that I write to SPI_TDR. As a result, the processor hangs on the while loop that checks the TDRE flag in SPI_SR. This while loop is located in the function SPI_Write() that belongs to the software package/library provided by ATMEL. The problem occurs arbitrarily - sometimes everything works OK and sometimes it fails on repeated attempts (attemp = downloading the same binary to the MCU and running the program). Configurations are (defined in the order of writing): SPI_MR: MSTR = 1 PS = 0 PCSDEC = 0 PCS = 0111 DLYBCS = 0 SPI_CSR[3]: CPOL = 0 NCPHA = 1 CSAAT = 0 BITS = 0000 SCBR = 20 DLYBS = 0 DLYBCT = 0 SPI_CR: SPIEN = 1 After setting the configurations, the code verifies that the SPI is enabled, by checking the SPIENS flag. I perform a transmission of bytes as follows: const short int dataSize = 5; // Filling array with random data unsigned char data[dataSize] = {0xA5, 0x34, 0x12, 0x00, 0xFF}; short int i = 0; volatile unsigned short dummyRead; SetCS3(); // NPCS3 == PIOA15 while(i-- < dataSize) { mySPI_Write(data[i]); while((AT91C_BASE_SPI0->SPI_SR & AT91C_SPI_TXEMPTY) == 0); dummyRead = SPI_Read(); // SPI_Read() from Atmel's library } ClearCS3(); /**********************************/ void mySPI_Write(unsigned char data) { while ((AT91C_BASE_SPI0->SPI_SR & AT91C_SPI_TXEMPTY) == 0); AT91C_BASE_SPI0->SPI_TDR = data; while ((AT91C_BASE_SPI0->SPI_SR & AT91C_SPI_TDRE) == 0); // <-- This is where // the processor hangs, because that the SPI peripheral is disabled // (SPIENS equals 0), which makes TDRE equal to 0 forever. } Questions: What's causing the SPI peripheral to become disabled on the write to SPI_TDR? Should I un-comment the line in SPI_Write() that reads the SPI_RDR register? Means, the 4th line in the following code: (The 4th line is originally marked as a comment) void SPI_Write(AT91S_SPI *spi, unsigned int npcs, unsigned short data) { // Discard contents of RDR register //volatile unsigned int discard = spi->SPI_RDR; /* Send data */ while ((spi->SPI_SR & AT91C_SPI_TXEMPTY) == 0); spi->SPI_TDR = data | SPI_PCS(npcs); while ((spi->SPI_SR & AT91C_SPI_TDRE) == 0); } Is there something wrong with the code above that transmits 5 bytes of data? Please note: The NPCS line num. 3 is a GPIO line (means, in PIO mode), and is not controlled by the SPI controller. I'm controlling this line by myself in the code, by de/asserting the ChipSelect#3 (NPCS3) pin when needed. The reason that I'm doing so is because that problems occurred while trying to let the SPI controller to control this pin. I didn't reset the SPI peripheral twice, because that the errata tells to reset it twice only if I perform a reset - which I don't do. Quoting the errata: If a software reset (SWRST in the SPI Control Register) is performed, the SPI may not work properly (the clock is enabled before the chip select.) Problem Fix/Workaround The SPI Control Register field, SWRST (Software Reset) needs to be written twice to be cor- rectly set. I noticed that sometimes, if I put a delay before the write to the SPI_TDR register (in SPI_Write()), then the code works perfectly and the communications succeeds. Useful links: AT91SAM7X Series Preliminary.pdf ATMEL software package/library spi.c from Atmel's library spi.h from Atmel's library An example of initializing the SPI and performing a transfer of 5 bytes is highly appreciated and helpful.

  • Initializing SD card in SPI issues

    - by Sembazuru
    Sorry for the length of this question, but I thought it best to show as much detail to fend of questions asking if I had done A when I had already done A... ;-) I've had a look at the "micro-SD card initialization using SPI interface" thread and didn't see any answers that matched my issue (i.e. things I haven't already tried). I have a similar issue where I'm trying to access a SD card through a micro-controller's SPI interface (specifically an HC908). I've tried following the flow charts in the Physical Layer Simplified Specification v2.00 and it seems to initialize correctly on Transcend 1GB & 2GB and an AE&C 1GB card. But I'm having problems on 3 other random cards from my stash of old cards that I've used on my camera. My code is all HC908 assembler. I scoped out the SPI clock line and during initialization it's running about 350kHz (the only speed multiplier that the HC908 supplies at my low MCU clock speed that falls within the 100-400kHz window). Here are the results of the three cards that aren't completing my initialization routine (all done consecutively w/o changing any code or timing parameters): Canon 16Meg card (labeled as SD): Set card select high Send 80 SPI clock cycles (done by writing 0xFF 10 times) Set card select low Send CMD0 [0x400000000095] and Loop up to 8 times waiting for high bit on response to go low R1 = 0x01 (indicates idle) Send CMD8 [0x48000001AA87] and Loop up to 8 times waiting for high bit on response to go low R1 = 0x05 (idle and illegal command) Because illegal command set local flag to indicate v1 or MMC card Send CMD58 [0x7A00000000FD] and Loop up to 8 times waiting for high bit on response to go low R1 = 0x05 (idle and illegal command) because illegal command branch to error routine Send CMD13 [0x4D000000000D] (show status buffer) and Loop up to 8 times waiting for high bit on response to go low R1= 0x05 (idle and illegal command) Is the illegal command flag stuck? Should I be doing something after CMD8 to clear that flag? SanDisk UltraII 256Meg Set card select high Send 80 SPI clock cycles (done by writing 0xFF 10 times) Set card select low Send CMD0 [0x400000000095] and Loop up to 8 times waiting for high bit on response to go low R1 = 0x01 (idle) Send CMD8 [0x48000001AA87] and Loop up to 8 times waiting for high bit on response to go low R1 = 0x05 (idle and illegal command) Because illegal command set local flag to indicate v1 or MMC card Send CMD58 [0x7A00000000FD] and Loop up to 8 times waiting for high bit on response to go low R1 = 0x01 (idle) Send 0xFF 4 times to read OCR OCR = 0xFFFFFFFF Send CMD55 [0x770000000065] (1st part of ACMD41) and Loop up to 8 times waiting for high bit on response to go low R1 = 0x01 (idle) Send CMD41 [0x6900000000E5] (2nd part of ACMD41) and Loop up to 8 times waiting for high bit on response to go low R1 = 0x05 (idle and illegal command) Because illegal command, assume card is MMC Send CMD1 [0x4100000000F9] (for MMC) and Loop up to 8 times waiting for high bit on response to go low R1 = 0x05 (idle and illegal command) Repeat the CMD1 50 times (my arbitrary number to wait until idle clears) Every R1 response is 0x05 (idle and illegal command) Why is OCR all F? Doesn't seem proper at all. Also, why does ACMD41 and CMD1 respond illegal command? Is CMD1 failing because the card is waiting for a valid ACMD after the CMD55 even with the illegal command response? SanDisk ExtremeIII 2G: Set card select high Send 80 SPI clock cycles (done by writing 0xFF 10 times) Set card select low Send CMD0 [0x400000000095] and Loop up to 8 times waiting for high bit on response to go low R1 = 0x01 (idle) Send CMD8 [0x40000001AA87] and Loop up to 8 times waiting for high bit on response to go low R1 = 0x7F (??? My loop shows the responses for each iteration and I got 0xFF 0xFF 0xC1 0x7F... is the card getting out of sync?) Send CMD58 [0x7A00000000FD] and Loop up to 8 times waiting for high bit on response to go low R1 = 0x01 (idle and back in sync) Send 0xFF 4 times to read OCR OCR = 0x00FF80 Send CMD55 [0x770000000065] (1st part of ACMD41) and Loop up to 8 times waiting for high bit on response to go low R1 = 0x5F (??? loop responses are 0xFF 0xFF 0xF0 0x5F... again out of sync?) Send CMD41 [0x6900000000E5] (2nd part of ACMD41) and Loop up to 8 times waiting for high bit on response to go low R1 = 0x05 (idle and illegal command, but back in sync???) Because illegal command, assume card is MMC Send CMD1 [0x4100000000F9] (for MMC) and Loop up to 8 times waiting for high bit on response to go low R1 = 0x7F (??? loop responses are 0xFF 0xFF 0xC1 0x7F... again out of sync?) Repeat CMD1 and Loop up to 8 times waiting for high bit on response to go low R1 = 0x01 (idle) Repeat CMD1 and Loop up to 8 times waiting for high bit on response to go low R1 = 0x7F (??? loop responses are 0xFF 0xFF 0xC1 0x7F... again out of sync?) Repeat CMD1 and Loop up to 8 times waiting for high bit on response to go low R1 = 0x00 (out of idle) Send CMD9 [0x4900000000AF] (get CSD) and Loop up to 8 times waiting for high bit on response to go low R1 = 0x3F (??? loop responses are 0xFF 0xFF 0xC1 0x3F... again out of sync?) Code craps out because Illegal command bit is high. WTF is wrong with that card? Sometimes in sync, other times not. (The above pattern is repeatable.) I've scoped this one out and I'm not seeing any rogue clock cycles going through between MOSI/MISO transfers. Anyone have any clues? Need any more info? Thanx in advance for spending the time to read through all of this.

  • How do you control what your C compiler Optimizes?

    - by Jordan S
    I am writing the firmware for an embedded device in C using the Silicon Labs IDE and the SDCC compiler. The device architecture is based on the 8051 family. The function in question is shown below. The function is used to set the ports on my MCU to drive a stepper motor. It gets called in by an interrupt handler. The big switch statement just sets the ports to the proper value for the next motor step. The bottom part of the function looks at an input from a hall effect sensor and a number of steps moved in order to detect if the motor has stalled. The problem is, for some reason the second IF statement that looks like this if (StallDetector > (GapSize + 20)) { HandleStallEvent(); } always seems to get optimized out. If I try to put a breakpoint at the HandleStallEvent() call the IDE gives me a message saying "No Address Correlation to this line number". I am not really good enough at reading assembly to tell what it is doing but I have pasted a snippet from the asm output below. Any help would be much appreciated. void OperateStepper(void) { //static bit LastHomeMagState = HomeSensor; static bit LastPosMagState = PosSensor; if(PulseMotor) { if(MoveDirection == 1) // Go clockwise { switch(STEPPER_POSITION) { case 'A': STEPPER_POSITION = 'B'; P1 = 0xFD; break; case 'B': STEPPER_POSITION = 'C'; P1 = 0xFF; break; case 'C': STEPPER_POSITION = 'D'; P1 = 0xFE; break; case 'D': STEPPER_POSITION = 'A'; P1 = 0xFC; break; default: STEPPER_POSITION = 'A'; P1 = 0xFC; } //end switch } else // Go CounterClockwise { switch(STEPPER_POSITION) { case 'A': STEPPER_POSITION = 'D'; P1 = 0xFE; break; case 'B': STEPPER_POSITION = 'A'; P1 = 0xFC; break; case 'C': STEPPER_POSITION = 'B'; P1 = 0xFD; break; case 'D': STEPPER_POSITION = 'C'; P1 = 0xFF; break; default: STEPPER_POSITION = 'A'; P1 = 0xFE; } //end switch } //end else MotorSteps++; StallDetector++; if(PosSensor != LastPosMagState) { StallDetector = 0; LastPosMagState = PosSensor; } else { if (PosSensor == ON) { if (StallDetector > (MagnetSize + 20)) { HandleStallEvent(); } } else if (PosSensor == OFF) { if (StallDetector > (GapSize + 20)) { HandleStallEvent(); } } } } //end if PulseMotor } ... and the asm output for the the bottom part of this function... ; C:\SiLabs\Optec Programs\HSFW_HID_SDCC_2\MotionControl.c:653: if(PosSensor != LastPosMagState) mov c,_P1_4 jb _OperateStepper_LastPosMagState_1_1,00158$ cpl c 00158$: jc 00126$ C$MotionControl.c$655$3$7 ==. ; C:\SiLabs\Optec Programs\HSFW_HID_SDCC_2\MotionControl.c:655: StallDetector = 0; clr a mov _StallDetector,a mov (_StallDetector + 1),a C$MotionControl.c$657$3$7 ==. ; C:\SiLabs\Optec Programs\HSFW_HID_SDCC_2\MotionControl.c:657: LastPosMagState = PosSensor; mov c,_P1_4 mov _OperateStepper_LastPosMagState_1_1,c ret 00126$: C$MotionControl.c$661$2$8 ==. ; C:\SiLabs\Optec Programs\HSFW_HID_SDCC_2\MotionControl.c:661: if (PosSensor == ON) jb _P1_4,00123$ C$MotionControl.c$663$4$9 ==. ; C:\SiLabs\Optec Programs\HSFW_HID_SDCC_2\MotionControl.c:663: if (StallDetector > (MagnetSize + 20)) mov a,_MagnetSize mov r2,a rlc a subb a,acc mov r3,a mov a,#0x14 add a,r2 mov r2,a clr a addc a,r3 mov r3,a clr c mov a,r2 subb a,_StallDetector mov a,r3 subb a,(_StallDetector + 1) jnc 00130$ C$MotionControl.c$665$5$10 ==. ; C:\SiLabs\Optec Programs\HSFW_HID_SDCC_2\MotionControl.c:665: HandleStallEvent(); ljmp _HandleStallEvent 00123$: C$MotionControl.c$668$2$8 ==. ; C:\SiLabs\Optec Programs\HSFW_HID_SDCC_2\MotionControl.c:668: else if (PosSensor == OFF) jnb _P1_4,00130$ C$MotionControl.c$670$4$11 ==. ; C:\SiLabs\Optec Programs\HSFW_HID_SDCC_2\MotionControl.c:670: if (StallDetector > (GapSize + 20)) mov a,#0x14 add a,_GapSize mov r2,a clr a addc a,(_GapSize + 1) mov r3,a clr c mov a,r2 subb a,_StallDetector mov a,r3 subb a,(_StallDetector + 1) jnc 00130$ C$MotionControl.c$672$5$12 ==. ; C:\SiLabs\Optec Programs\HSFW_HID_SDCC_2\MotionControl.c:672: HandleStallEvent(); C$MotionControl.c$678$2$1 ==. XG$OperateStepper$0$0 ==. ljmp _HandleStallEvent 00130$: ret It looks to me like the compiler is NOT optimizing out this second if statement from the looks of the asm but if that is the case why does the IDE not allow me so set a breakpoint there? Maybe it's just a dumb IDE!
