Folks, I have a device that installs into another product and provides SRAM for code execution for the other device. The device my board plugs into has a fixed 500ms RESET generator that hold off the host device CPU for that much time. During this ...

Folks,Once I had my SD card working, I went to add in the Formatting option. When I enabled the format SD Media option in the FileX config, it generates this below, even though my settings are set to FX_ENABLE_EXFAT. Shouldn't this auto-generate the...

Folks, I started off with the H573i discovery board demo as reference for the MSC + SD card (with ThreadX). I don't have the Discovery board since in my application I needed those CC1, CC2 USBPD pins for something else. So I ran a board of my own (u...

Hi Haithem,I have not been able to find the SDMMC DMA setup within the Cube config IOC generator.I read in the reference manual that the SDMMC has its own dedicated DMA independent of the GPDMA1,2.How do I enable the DMA for the SDMMC in Cube? Once ...

@Nicolas P. @FBL I found the issue - one step further. CubeMX defaults the IO Speed setting for the MCO1 pin to low speed when it is enabled within the pin config (chip map). This is done in the MX_GPIO_Init. But the setting for the SystemClock is...

@Nicolas P. @FBL Found the issue solution for the MCO1 startup.If I use it as configured out of CubeMX, it places the MCO division and source setup in the SystemClock_Config which is the very first thing on code startup. There is some kind of intern...

@Nicolas P. @FBL Question about the MCO1 signal output. In my application I started it off at 20MHz output. That worked perfectly. Clean square-wave. When I tried to go to 40MHz, the signal drops to only 300mV vs the 3V swing I get when at 20MHz...

@FBL could you send the IOC as the following: USB-MSC (device), no UCPD, SDMMC1(SD Card-4bit), STM32H563ZIT6. That was the specific combo I was in need of. The example you sent for the IOC turned out to be the Host mode.While it did a Git commit t...
