NuttX ported to STM32H745I-DISCO board

This weekend I ported NuttX to STM32H745I-DISCO board and got LVGL working on it.

It is a nice board to run NuttX because it has a big LCD display with resolution of 480×272. Soon I’ll submit it to mainline.

Compiling and flashing:

$ ./tools/configure.sh stm32h745i-disco:lvgl
$ make
$ sudo openocd -f interface/stlink-v2.cfg -f target/stm32h7x.cfg -c init -c "reset halt" -c "flash write_image erase nuttx.bin 0x08000000"

Open minicom and configure it to use /dev/ttyACM0 115200 8n1
