Title: Problem UI with STM32H734ZIT6
Post by: yeson on 25. August 2022, 07:21:23
Processor STM32H743ZIT6V The DFU can see in PC but the Dfuse Demo v.306 cann't Program and I check some key piont.
Power 3.3V is available.
Reset (25 foot) C94 with 57KOhm works - rises to 1.9V.
The IC5 (ASTX-H11) 3-pin provides a 16MHz signal with a 1.7V amplitude.

After that I programmed with ST-Link V2.
Bootloader to 0x08000000 Fireware to 0x08060000. I think to MCU cann't not run

I have not programmed STM32 for a long time but I remember that STM32*7 sometimes have scrambled BOOT_ADD0 and BOOT_ADD1 which must be set manually with stlink. I am working on Linux console and havbe not any skills on Windows applications.

In the Option bytes
BOOT_ADD0 = 0x08000000
BOOT_ADD1 = 0x1ff00000

Is it the correct address for booting?

Pse look here (https://www.amateurfunk-sulingen.de/forum/index.php?board=18;action=search) and enter pattern "BOOT_ADD".

I read the datasheet. edit the Boot address option bytes. the DFU work.
BOOT_ADD0(H) 0x0800 Boot from(H) 0x08000000
BOOT_ADD1(H) 0x1FF0 Boot from(H) 0x1FF00000

The DFU mode can Program. But MCU still not working.The Hold broad current just 50~60mA. The P6 is took off.

Test if MCU bootloader works (this does not depend on correctly working LCD and/or clock oscillator:

Press and hold BAND+ - button, press and hold power button. After 3...5 seconds relase BAND+ button.

If TRX is now in DFU mode (without P6 set!!!!) MCU is working.
