Was a thread yesterday about STM32H723 and Winbond W25Q128 seems to disappeared from general visibility.I think there's were two spam posts against it, which I had flagged for deletion, but as I say now I can't see the thread, or the posts / alerts r...

I've complained about this before, and got nowhere. It's still completely unworkable. When can we light a fire under the developers to get this addressed? Showing FIVE potential matches might work in a system with SIX users, it is not viable in one w...

Please use the </> icon / tool to paste in source code.Not sure why the stack would get corrupt, perhaps look at other interrupts / callbacks and what they might be doing that would damage the stack frame.

Please use the </> icon to paste in code, not attach as bitmaps, thanks.I'd perhaps be concerned about how you have it wired to the STM32, the pins, the RS485 driver, and how you gate that as an output.Use a scope or logic analyzer to review the sign...

>> I chose PH5 (Timer12 Channel 2) ... Alternate function is available for PH9 Ok, if you in fact used PH9 that would make a lot more sense

Well the STM32F1/SPI implementation isn't going to be particularly fast, and the FAT32 / EXFAT tables can get colossal.Does the F1 part you've chosen support SDIO ?The transfer size can also make a big difference to how efficiently the OS and the car...

Ok, but what address is the allocator furnishing here?Can you instrument __sbrk ? Or whatever is serving up space?Sounds like something is walking into the end-of-memory. The FMC setting will scope the address decode space of the SDRAMWhat are the in...
