Hi Marius, Sorry for the late reply, holidays here. Did lots of testing and here's one thing I observed wrt sd cards and let me share the same with you: So I tried bootloading process using various SD cards, 5nos 4GB, 2nos 8GB and 1 32GB. 4GB sd cards behaved similarly as mentioned above - 1 to 2/10 times the bootloader is unable to mount/access sd card. While the 8GB sd cards have not displayed any such issue - tried around 250+ times. I've also tried with 32GB sd cards, was not able to replica…

Perfect!

I tried enabling interrupts at start OS_DecRI(); and even that didn't help. Anything else that I can try? Edit: If I check the disassembler, here's the sequence 1. OS_TerminateError 2. OS_InitKern_STD 3. OS_Delay ------ The code gets stuck here seems like a while(1) loop 4. OS_SetTaskContextExtension 5. OS_WaitEventTimed

Hi Til, Thanks for the quick reply. That's exactly what I'm testing, by removing : OS_IncDI(); I don't call the OS_Delay routine. It seems to be an internal call. Yes, ours is a full licensed copy - object code license and hence I was unable to dig deeper. *Edit: Even after removing OS_IncDI(); the issue persists. Regards, Gautam

Hi, We're using embOS v4.22. I observed that sometimes ie 1-2/10 times the code gets stuck in OS_InitKern_STD; precisely in: OS_Delay called after OS_InitKern_STD. The portion of the attachment behaves like a recursive code forever. Can you help me understanding why this happens? My Main looks like this: Source Code (12 lines) Regards, Gautam

Hi Marius, PFA Log. FYI While logging my bootloader was never able to read the SD card contents. Only after disabling logging did the bootloader flash the controller. Regards, Gautam

No one?

Hi, We're using emFile version: V4.04a What we observed was 1-2/10 times the code is unable to mount the SD card as it gets stuck at FS_Mount(""); Any hint on what might be happening? I've attached the code snippet. Regards, Gautam
