Hello,I'm trying to copy an existing project to a new directory tree to do modifications there (and leave the original unchanged).It seems like copying all the files to the new tree location and opening the .ioc file should work, but when I try that ...

Hello,I'm having weird problems with code crashing, perhaps related to how I have IRAM1/IRAM2 set up in my project:Looking in the reference manual, I see that the SRAM starting at 0x2000_0000 is the DTCM_RAM on TCM interface (data RAM?), the SRAM sta...

Hello,I was trying to use USART1 in a project with STM32H742VIT6 but decided to use LPUART1 instead. I found that using the same BRR computation the baud rate is coming out MUCH slower (it's around a factor of 51 slower). LPUART1SEL is in the reset...

Hello,I am developing a project using STM32H742VIT6.I have tentatively tried to configure SPI on PA4-7 outputs and USART1 TX on PA9 simultaneously. However, when I try to implement this configuration on STM32CubeMX, it automatically places USART1 TX...

I am trying to do disk i/o with a FAT32-formatted SD card (32GB ADATA) using SPI on a STM32H742VIT6.The disk_initialize() function in diskio.c does not complete because it looks like the wait_ready() function is always timing out.static int wait_read...

I edited the stack size in startup_stm32h742xx.s. It used to be 0x400 and I changed it thus:Stack_Size EQU 0x800Problem solved!I'm still not sure why this project needs a bigger stack than an equivalent project on an STM32F3* MCU, but I'll take...

OK I think I'm getting somewhere now.I’ve reverted the code to the original static declarations and removed the malloc()/free() calls.The IRAM1/IRAM2 settings are as in the screenshot at the top except that I've changed the IRAM2 size to 0x60000.In d...

I corrected the earlier post. Sorry for the confusion. I wonder if you can think of any reason why the previously-declared static structure would have been overwritten by memcpy() given the code as now quote above.Thanks!

Sorry! I copied the new version of that line of code and forgot to add the ampersand. Of course it was “&img_hdr” in the original code as you suggested.

I already know one line of code which was causing one of these io_handle structures to be overwritten (I zeroed in on it by setting breakpoints and examining memory). It was the function get_curr_frmw_info() illustrated here: __NO_RETURN int main(vo...
