Resolved! Any limits on flash selection for STM32N6

From my understanding all STM32N6 chips need a external flash chip and there's a static stage 0 boot loader.  So if this is true is there any limitation's on the brands of flash or speed/address bit size limitations? With the previous stage 0 bootloa...

Using external RAM with STM32U5G9-HSPI

Hi Everyone,I am working on a project with TouchGFX. I'm working with STM32U5G9ZJT6 and I have an external RAM APS12808L-OBM-BA connected via HSPI (Fclk-hspi 100 MHz) in mapped mode. The project is working, but the image animation are not working wel...

STM32U5 SPI3 (SmartRUN domain) + GPDMA

On a stm32u5, the SPI3 is in the SmartRun domain, which is designed to work down to STOP2 in autonomous peripheral mode with LPDMA. I'm now wondering if it is also possible to use SPI3 in autonomous mode with GPDMA but only to STOP1? Or do I need to ...

Resolved! STM32H7S7L8H6H XSPI instability

IssueHigher ambient temperatures cause communication malfunctions with XSPI memories.DetailsOur design is heavily adopted from STM32H7S78-DK which also has the same issue described below.The application uses memory-mapped mode for both Flash and RAM ...

HAL_UART_Init() assert with LPUART at high baudrate

I call HAL_UART_Init() with LPUART1 at 20Mbaud but when I activate assertion it fail at IS_UART_BAUDRATE().The IS_UART_BAUDRATE() is not correct for LPUART that can have a baudrate up to 53.3 Mbaud.Also for UART, the comparaison in IS_UART_BAUDRATE()...

stm32U585 + 2 x APS25608N OSPI - speed problems

Hai All!I use 2 pieces of APS25608N PSRAM on OSPI bus with memory mapped mode. The MCU run at 1.8V, 160MHz system clock. Previously, I used APS12808N at 80MHz and 3.3V VDD without any issues.Currently, the PSRAMs run at 50MHz, but need to speed up to...
