Hello
I recently purchased a Sparrow pcb set and stuck the stm32h743zit processor. I stuck the codecs, the eeprom, the oscillators - including the 32,768 Khz. I got the butloader, then at location 0x08060000 I wrote the software, but when starting it is locked, I did not know how to proceed. It remains only for the welcome message. Where did I go wrong, what should I do? Because it crashes on startup, I can't customize the software with the help of the butloader but with the st-link. I loaded correctly for the H7, but it stops at startup and only the welcome message and the red LED remain.

The firmware got it correctly but only through ST-link. That's how it stays, the bees stop it again.

Thats NOT normal. As you can read a page before in this thread. There is NO need for the ST-Link at all ! It all can be done with just the DFuse tool !
Make the P6 bridge, bring the board into DFU mode and flash the right bootloader. Bootloder files as well as firmware files are different for F7 or H7 CPUs ! Check the bootloader message if you like and after that flash the right firmware with the DFuse tool. Thats it !
Procedures can be seen here:
https://www.amateurfunk-sulingen.de/forum/index.php?board=15;action=display;threadid=551;start=75
https://www.amateurfunk-sulingen.de/forum/index.php?board=18;action=display;threadid=1055;start=0
The ST-Link tool is only needed if you (or testing) messed up the CPU registers. This can usually be seen when the board did not go into DFU mode anymore even with the bridge set on the UI.
In that case you need to restore the registers (Andreas posted them the page before) to bring the board back into DFU mode.
Then repeat the whole above procedure with the DFuse tool to flash bootloader and firmware.

Hello!
I have done everything you advised me to, but the same thing keeps happening - the welcome message lights up, it stays like that, the LED is on, red. I have checked that everything works fine, but it doesn't go past the welcome message.

Hi
All s OK
I also have this problem. You need to load the bootloader and firmware again.
