I'm working with a STM32H723ZG and trying to set up SPI2 communication.I tracked down the issue where my LL_SPI_SetMode(SPI2, LL_SPI_MODE_MASTER) call does not set the Master bit in SPI2_CFG2 to 1, as intended (see Test #1 below). However, if I call...

I'm somewhat new to scatter files and I'm trying to understand them better by doing some tests on a ST32F765 project (with 2mb flash at 0x0800 0000 - 0x081F FFFF).This scatter file works OK:LR_IROM2 0x08100000 0x00100000 { ; load region size_regi...

I'm looking for a way to detect which device part number (EX: STM32F765...) is connected via the USB DFU bootloader before programming the device (as a sanity check to make sure the file is appropriate/compatible). I can see the VID/PID/REV and Opti...

I'm using the USB middleware for a STM32F765 MCU application. I am able to use the function USBD_CUSTOM_HID_SendReport() for transmitting data payload from my application to a USB host, but don't currently have visibility of if/when the data prepare...

Thanks, yes the SPI is disabled and IOLOCK is off before making these changes. This issue appears to be a result of the following 4 conditions:- SSIOP bit being 0 (low level active for SS)- SSI bit being 0 (SS input low)- SSM bit being 1 (software co...

Apparently, there is some issue with the NSS configuration and a MODF (mode fault) is being generated the first time the SPI2 is switched to Master=1. That MODF automatically switches SPI2 to slave mode (Master=0). I guess when the SetMode command ...

I ran into this issue and it was caused by firewall protections that geoblocked domains from Switzerland (where that file seems to be hosted).

Thanks!Regarding #1, I suspected that might be the case.Regarding #2, it's too bad there isn't a way to directly set those option bytes when doing the flash download from the IDE, but I'm sure there are very good reasons for it.

Thanks, that is super helpful! I see that the BOOT_ADD0 (in FLASH Option Bytes) appears to be set for the ST default value of 0xFF7F 0080 (ITCM-FLASH base address). That should cause a boot address of 0x0020 0000 ("Boot from Flash on ITCM interface...
