Have a device built around an 32f429 which appears to be hard faulting too infrequently to catch on the bench with debugger attached -- but have lab personnel running all day and getting the errors, not infrequently enough.I can use some BKUP registe...

The documentation I have says the Ethernet calculation with 0x4C11DB7... but I don't get results matching what I get from any other calculator. To remove any endianess or mirroring questions I've tried 0x00000000 and 0x66666666 (e.g.). All calculat...

Right. I've got that address -- and so can find the line of code, and the function containing it... say function "ucalledme". ucalledme might turn out to be some utility function, or otherwise be insufficient to be of much use. It seems that there sh...

Hi Jan,Thanks for your reply. I've read the info you point to in PM0214, but my problem isn't what is stacked during exception entry. I'll look more closely at the link you provided to see if there are hints there.I'm trying to get some more info out...

These 2 lines of bash muck the hex file just right:read c1 c2 < <(awk -n '/^[ ]*CHECKSUM / {printf "0x%X 0x%X\n", $2, $2+4}' $Build_Map)srec_cat $Build_Hex -intel -exclude $c1 $c2 -STM32 $c1 -output wcrc.hex -intelWould rather get the CHECKSUM from t...

Sorry,I don’t know what you mean by driving it backwards. What I see on this thread are the 2 functions Crc32 and Crc32Rev and nothing about ‘driving backwards’…. Unfortunately, I also don’t see that the value returned from Crc32Rev, when input into ...

Hah – I didn’t realize that. I guess that driving it backwards involves setting the initial CRC to zero (and running on a2 then a1), and I can figure out just how to use CcrRev for determining the bridge value ….. trying now….

Want to figure out how dig down into stacked LR and SP values on an STM32f429 programmed with Keil tools.

Which 32 bit CRC does the CRC calculation unit on the stm32f429 calculate?
