Hi all,Board: STM32H745I-DISCOIDE: 1.16.1 I am facing some issues with trying to execute code on the SDRAM. I have a 2nd stage bootloader that loads the user application onto QSPI located at 0x9000 0000. After that, I copy the user application code t...

Hi,I have resolved the issue and found the root cause.. I had to do 2 things to make code execution work for STM32H745 on SDRAM.1. Remap the SDRAM by executing this command below in stm32h745i_discovery_sdram.c, MX_SDRAM_BANK2_init function/* SDRAM b...

Hi SofLit, I have found that before and after the jump, the SDRAM_SDCLK is changed from 100MHz to 33MHz as shown in the attached screenshots. My user application might have changed the clock setting that was set by the bootloader.Regards,Reuben Goh

Hi MM..1,Yes I note that. When I am compiling to run the code on SDRAM, my linker script of my code section is pointing to SDRAM 0xD0000000. The Vector table is also pointing to the SDRAM 0xD00000000. So the code i copy from QSPI, the application pro...

Hi SofLit, I tried to read the SDRAM register before jump usingserial_debug_printf("%08X\n\r", FMC_Bank5_6_R->SDCR[0]); serial_debug_printf("%08X\n\r", FMC_Bank5_6_R->SDCR[1]);but how do I read the registers after jumping? As nothing executes after ...

Hi SofLit,I have disabled the DEINIT functions in the sdram.c file and tried to run it. Seems to be better, as I am able to read the SDRAM after the jump. But my program still unable to execute. I suspect that the MDMA interrupt might have triggered ...
