Hi everybody.I'm facing a strange behaviour on my application. I'm using a STM 23H562, and I'm usign LL library to drive a SPI display (classic iLi).I take the example from c:\Users\Massimo NUCLEO-H533RE\Examples_LL\SPI\*and the display do what I wan...
Dear all.I've implemented a M3 and M4 program ( drive a iLi display and 485 port) now I'm porting it to the H5 (H562RGTX).One of the latest issue I'm facing is the jump from bootloader to application. In M3/M4 i used only LL, and the jump has no prob...
Hello to everyone.
I'm working on a display interface, changing from M3 -> M4 -> H5 CPUs. The issue appeared on all type(it's a HW issue?)
At the beginning I can connect, debug, program and so on. Bt after some operation, I can't continue. I stil...
Hi to everybody.I'm struggling to figure out this issue: I got a "NMI_Handler" error...uint32_t *p = (uint32_t*)0x08080000UL;
uint32_t val = *p; //here jump to NMI_HandlerIf I put the addr to 0x08070000UL (e.g.) no probelm.I'm using a STM32H562RGTX ...
Hi to everybody.I'm using H5 and FREE RTOS. I'm porting a project from M3 , than M4 now to H5. I used LL for all the periferals, but moving to HAL isn't a probelm (... but I prefer LL!).On M3 and M4 I used a timers to "serve" the RTOS scheduler, the...
I'm using a iLi9341 SPI display 320x240. It work only with SPI. With M4 DMA it work w/o problems.SPI speed is 30MHz, but if I reduce there is no difference.Because the total display memory is 320x240x2 byte = 153600B. I need 2 full DMA and one of ~22...
Hi Imen.DI investigated in interrrupt vector table, because also any other interrupt (e.g. USART) crash it.Re-type the "#define VECT_TAB_OFFSET 0x08020000UL" and now it work!Probably some typo create the mistake.Thanks for the help.
You're right!But after posting my colleague realize that a cable isn't well inserted. It's a mistake, after 2-3 month of tests.And I'm sure I can't realize it until I made this post :frowning_face:
@Pavel A. @STOne-32 @Tesla DeLorean Yep! The situation is in a custom bootloader (I'm doing a porting from a M4 solution).If the bootloader check the CRC32's application in flash it simply remain in bootloader and don't jump. What Is necessary is doi...
Thanks Tesla DL.I tried with full chip erase, then execute again the test, and now it work wo NMI interrupt. So you're right.Now the question should be: How I can detect if the flash (in any point) is not corrupted? Because tn that case the only way ...
