Cool, that would be:

9.54 mA in normal running mode
1.32 mA in lightsleep mode ?

What was the system clock setting ?
Which Micropython FW did you use for testing ?

Hi, I think that I managed to fix the missing factors of the clock tree. FW builds now, but no repl at the usb port. I think It could be reconfigured so that the repl is on one of the Uarts. However, I would prefer to have it on usb - any idea what I forgot in the config ? If you want to check out, ...

First I would check if this board does in fact have a 25MHz crystal as Ihave brought these cheap boards from China with advertised 25MHz crystal but then to find all my timing for my programs were out because it really had a 8MHz crystal and once I change the clock setup to suit a 8MHz crystal then...

Hi, just received my NUCLEO-STM32H7A3 board ( https://www.st.com/en/evaluation-tools/nucleo-h7a3zi-q.html ) and tried to build MicroPython for it. I used the board config NUCLEO_H743ZI as a starting point but soon had to find out that the H7A3 is still missing in the current cubeHAL of the stm32lib....

Thanks for the info.
Have found 2 similiar boards on taobao. Since the pin headers are labelled with stm32 pin names it might be ok not to have the schematic.
I will try to order one and in case I succeed I will probably open a new thread here.

Hi, I have found this board : https://de.aliexpress.com/item/33031567472.html?spm=a2g0o.productlist.0.0.6c0733be3c5Uoe&algo_pvid=c6d53be7-8884-4bbb-8b05-d5b72ee2de10&algo_expid=c6d53be7-8884-4bbb-8b05-d5b72ee2de10-29&btsid=be127f85-2e4f-4925-a5f3-e1c66f840a89&ws_ab_test=searchweb0_0,searchweb201602_...
