I try to build a code example where I can execute directly from external OctalSPI flash.I use HAL project "XSPI_NOR_MemoryMapped_DTR" as reference and starting point:It works fine: I can write (flash) and read back external QSPI memory. I can also ex...

FYI,you can build, load, start and debug also the "Appli" project (not just as FSBL).The linker script (selected as default) "STM32N657XOHXQ_LRUN.ld" loads and executes in the same way.In order to avoid this warning about "LOAD segment with RWX permi...

It looks like (based on PCB and schematics) - I cannot run the VDDIO (all IO pins) with 1V8.No option on this board to jumper IO voltage as 1V8 - why not?"rrrrrr": I was thinking to change all my projects to this great board (speed, memory size), e.g...

I am not yet the full expert (I have not read all docs, just trying with a simple project).It looks like, what I have in mind is maybe not possible.Goal:I want to have all my code on external QSPI memory (because the chip does not have an internal co...

My project works as FSBL. I can also generate it as an Appli project (using the linker script "STM32N657X0XQ_LRUN.ld" (as default selected)), similar code works with ST-LINK debugger.But how to generate a signed image and flash to external QSPI memor...

My experience:You should see the CMSIS version when reading some "readme.txt", "readme.md" or other files coming with it.Often, there are also comments in the C-code files for CMSIS to realize the version.Important: CMSIS v1.x vs. v2.xx:Changing to a...

No idea, just thoughts...OK, you use volatile. Very important here to use volatile (a shared variable modified outside the loop code - compiler should not optimize to ignore USBTimeout if no changes seen in code).Operator precedence:==USBD_Busy && US...

BTW:Even your FatFS system does not support 1TB capacity - you could consider to format the 1TB with different "partitions": you configure, for instance, 5x different partitions (each as 64GB), so that they appear on FW as five different "devices".Bu...

My five cents:Assuming the HW works, e.g. you can insert the 1TB SD card into an SD card socket (or are you talking about SD card as USB adapter?),there is potentially an issue which FW/SW you use to make use of this 1TB SD Card:if you use FatFS with...

Just "follow" the compiler warnings:1. "warning: implicit declaration of function 'MX_ADCQueue_Config'": You call a function which is not declared. Potentially, forgotten to include a H-file or to declare this function (as available somewhere else...
