Re: F7disco BSP for LCD causes bus error.

I'm having an issue finding "lcdF7D"... When you say "import lcdF7D"... searching high and low, I can't find it. Can you tell me where it is hiding?
Thanks

Re: STM32 F7 Discovery

Thanks for the link!
I also found "Boot0"(with a little help)... If you look around U5, you'll see a missing resistor R42(0201 size). All you do is apply a solder bridge and suddenly can erase at will. When you're done, just remove your solder bridge...
Your mileage may vary,

STM32 F7 Discovery

Yes, they have micropython for this board but it seems the nice LCD isn't supported. Has anyone gotten the LCD incorporated into their code. I have the STM32 F746 Discovery board.
Thanks,
Jim

loading STM32F407G-Disc1 issues

OK, I had an older STM32F4-Discovery board I had loaded micropython without any issues. So today I got a new board (STM32F407G-DISC1) from Mouser. After many attempts to load micropython, the micro USB port is still "dead". (Yes, I converted DFU to HEX using DFuSeDemo) I've been using my trusty Wind...
