Hello, We are using the STM32H747AI on a custom board and attempting to enter standby mode for power savings. The system supply is configured as "SMPS supplies LDO (no external supply)" to be able to use the boosted performance at 480MHz, but the chi...
Hello STM, I'm working on a project using the STM32H7R3L8H6H MCU with a PSRAM chip connected via HEXASPI to XSPM1. I'm encountering massive issues with the PSRAM initialization, which I described in a different post. I found a discrepancy between the...
Hi,Ref.manual (RM0477 Rev 8) in chapter 32.3.3 PSSI clock saysIn case when PSSI transmitting data, then RDY pin is input.Datasheet (DS14360 Rev 2) shows setup and hold time of RDY pin (input) referenced to rising edge as well as data pins (outputs).I...
I am trying to use stm32flash to program my board over UART. I understand that the board needs to be in boot mode in order for this to be accomplished, so using the STM32CubeProgrammer I have tried setting the resisters appropriately. BOOT_lOCK: set ...
I tried flashing a project created for the STM32H745I-DISCO board in CubeMx. I configured clock speed for the M7 core to 480MHz and the M4 core speed to 240MHz. After flashing, if i disconnect the board, the deadlock occurs. Then i have to pull up th...
Hello,I implemented a virtual com port using the usbx stack for the stm32U575 in standalone mode and it basicaly works.My problem is that I just can't put more than 8 bytes in the TX buffer at the time. If I do the program gets stuck (in the main loo...
I am working on an application where I plan to relocate all non-safety modules to the CM4 core. To achieve full safety, I need a mechanism to lock the peripherals so that the CM4 core cannot access any peripherals configured in the CM7 core, includi...
Can anyone comment on the prologue and epilogue of following CM7 code, particularly the content of r7 when the routine returns? { 0: b480 push {r7} 2: af00 add r7, sp, #0 if ((ANADIG_MISC->MISC_DIFPROG & ANADIG_MISC_MISC_DIFPRO...
Hi Team,I am observing a shift in a data each time i am sending same data from ESP8266 master to STM32f103RCT6 slave controller but each time i am getting different data and seems to be the shifted data as i can see some part of strings sent. I have ...
