Thanks for the quick response again. I will be away from my desk until the new year but I will post with an update to answer your questions when I get back.

Dave, Thank you for your response. To try to clarify, the board I am developing on uses a F427 (running the F429DISC port) and two USB PHYs: a USB type-B PHY that currently is only supplying power to the board, but has its DM/DP pins connected to the F427's PA11/PA12 a micro-USB PHY that has its DM/...

I would also like to know how to remap the USB pins. I am using the STM32F429DISC micropython port on a custom board and would like to use PA11/PA12 as D-/D+ instead of PB14/PB15. The only reference I can find to these pins is a comment in mpconfigboard.h: "THE HS USB uses B14 & B15 for D- and D+". ...

Thank you all very much for the quick replies!

Hello, I will need to flash a large number of boards with micropython, so I am trying to streamline the process as much as I can. Is it possible to have an initial main.py baked into the firmware that can then be changed later through the typical fashion (edit the source through the REPL or mounted ...

I got the LED issues to work (in part by changing the LED values in mpconfig.mk, and in part by realizing that the board's LEDs are active low and thus need to call off() to turn on). Now I am trying to get the board's UART to work. I tried replacing the pin values in mpconfig.mk from those used by ...

So I've got micropython successfully running on the custom F427 board using the unmodified F429DISC build. I have access to the REPL and the board shows up as a flash drive in Windows where I can edit main.py. However I cannot toggle the LEDs on the custom board like I am able to on the discovery bo...

Thanks for responding. This would actually be for a non-commercial, custom board. Does that make a difference in what would need to be altered from the F429 Discovery files?

Hello, I have a STM32F427 that I would like to get micropython running on. I am not sure how exactly to go about this - my idea is to take all of the files marked as *F429 in the /ports/stm32/boards/ directory and use those as a template, along with the datasheet for the F427, to add new files that ...

After two days of trying to troubleshoot, that fixed it! Thank you!
