ChibiOS Free Embedded RTOS

Hi,

I have a very strange problem. My program is working ok with an older toshiba 2GB micro SD card and with the newer one from the same manufacturer(2GB) I get errors.
I was able to debug the problem and found that it sometimes fails here while trying to read from the card.

if ((SDIO->STA ...

Thank you, netifapi_dhcp_start() is working for me.

Any idea how to start the DHCP in the lwip demo with STM32 and ChibiOS ?

I added this in lwipthread.c but the program halts somewhere in dhcp_start!

Yes, it is the stack I made it bigger and is ok now.

How can I check the stack of each thread in IAR and also the call stack of the threads it could be very useful?

Todor

Yes it is enabled, but still the same result. I suspect there is something in the fatfs port. Because in one of the threads I do fs_write if I remove it works......

This is called in chSysTimerHandlerI which calls chSchReadyI.

Let me explain what I have to get a better idea I have two threads
1. the first does chEvtWaitOneTimeout
2. the second does chEvtSignalFlags the first one
3. the second goes to chEvtWaitOneTimeout waits for the first to signal it
4. the ...

ChibiOs stuck in function chSchReadyI: (chschd.c) because cp->p_prio = 0 and tp->p_prio = 0

do {
cp = cp->p_next;
} while (cp->p_prio >= tp->p_prio);


Any Idea why this happens?

I suspect that there is problem with :
chEvtSignalFlags and chEvtWaitOneTimeout
Or something gets very fast do not ...

I found the problem was that I was not using proper tx/rx data pointers for the I2C DMA.

I am getting unhandled exception while doing I2C transfers, how can I find what is the cause if it is the DMA or something else?

Todor

Thank you. Yes, I saw it in the code.

Any, idea for using the DCMI on the STM32-E407, drivers, samples ?

Best regards,
Todor
