DUTY-CYCLE of QUADSPI CLK changed to 25% after 4GB indirect read
Hi ST team,I'm using STM32H743IIT6 with REV_ID=0x2003 and encountered a problem. Quadspi dual-flash indirect read mode is used for continuous reading data from external. According to RM0433, If QUADSPI_DLR = 0xFFFF_FFFF and FSIZE = 0x1F (max value in...
Resolved! How to enable the STM32N657X0 dcache using the STM Cube IDE?
Hello:I think I have found how to enable the i-cache on the STM32N657X0 using the STM Cube IDE through using the Pinout & Configuration of the project. Two questions:1. Is the icache actually enabled, or did I just made it available to be programmed?...
Resolved! STM32U5G9NJ-DK1: OCTOSPI Auto-Polling Timeout in OctalPollingWEL() for Macronix Flash
Hi,I'm encountering an issue with OCTOSPI auto-polling on the STM32U5G9NJ-DK1 Discovery Kit while following the "Octo-SPI FLASH in Regular-command protocol example" from AN5050 (Rev 12, February 2025). Specifically, in the OctalPollingWEL() function,...
