Hello,another day, another N6 "issue" :)I want to do RAM to RAM copy by HPDMA, but the data never get copied from Src to Dest, Dest always stays unmodified. I have checked the 'DMA_RAMToRAM' example for N6 and went from there, but with no success.DMA...

Hello,I have a problem with STM32N6. When trying to access any TCM (ITCM/DTCM) the CPU immediately crashes to the Hard_Fault. Do the TCM memories need to be explicitly enabled or something? From my experience from STM32H7, it was never needed. I've l...

Hello,I'm trying to do pattern generation on GPIO port using DMA timed by TIM trigger, but I cannot make it running.My code:TIM2 INIT void MX_TIM2_Init(void) { __HAL_RCC_TIM2_CLK_ENABLE(); HAL_NVIC_SetPriority(TIM2_IRQn, 3, 0); HAL_NVIC...

Hi,I have bought the STM32H747-DISCO kit for testing and I want to test at the max frequency (480MHz). I'm aware of the requirements for the 480MHz, I have followed the user manual:Desoldered and soldered relevant SBs for LDO operation.Updated the co...

First of all, you have configured your QSPI in 1 data line mode, which in turn makes it just a normal SPI. No point of using QSPI for this.Quick glance through the Datasheet of the DAC shows, that the DAC does NOT support QSPI (well, okay, technicall...

Hi,no, QSPI slave is not possible on STM32. QSPI interface is not intended for this purpose on STM32. It is mainly to connect external memories. And possibly displays. In both cases, you are always the master. How much bandwidth do you need? Why do y...

@RomainR. Thank you! This works.I realize, that the M55 core is different from M7 core. But I just never knew that the ITCM/DTCM memories need some kind of "init". I've modified your snippet to also init ITCM memory/* Clear I-TCM */ ldr R0, = 0x100...

Update: I have also tried to load the ITCM mem "directly", without the intermediate step of loading from ROM/RAM and this works, surprisingly. When debugging, I can see the SP switch to 0x10000000 and executes the code in ITCM normally. Really, reall...

Isn't it the place where the STM32N6 expects the binary "signature" using STM32_SigningTool_CLI.exe? And the offset shall actually be 0x400 (1kB)? Because that's the size of the signature. So it is maybe unreadable/unusable by design or something lik...
