Hi @acassis

Who is/are responsible for Nucleo-h743zi2 board? 

I think, If this is an officially supported board, then there should be at 
least 1 person having this board and testing all the published configurations 
for every release and take the speech at situations like this.

Perhaps you may remember when I started dealing with Nuttx about a year ago I 
had similar problems with running stm32f746g-disco:lvgl configuration and I 
asked help here https://github.com/apache/incubator-nuttx/issues/1643 , I 
couldn't get a help but fortunately Jonathan Gonzaga gave a hint upon my 
question here at LvGL forum 
https://forum.lvgl.io/t/lvgl-nuttx-touch-screen-performance/1498 , I changed my 
arm toolchain (arm-none-eabi-xxx) to a suitable release then my firmware worked 
very well. I thanks to Jonathan very much because on this occasion I learned 
that changing the toolchain may be a solution sometime and I recently used the 
same trick in an esp32 project successfully.

There may be a similar toolchain mismatch here so I think it would be proper if 
one of maintainers tests my nuttx.bin and his own compiled firmware with the 
present master branch on his Nucleo-H743zi2 board.

BR,
Murat

Hi Rushikesh,

I think you are doing the right steps, but just to confirm:

$ make distclean

$ ./tools/configure.sh nucleo-h743zi2:nsh

$ make menuconfig     (this step is optional, just confirm that Device
Drivers  ---> [*] Serial Driver Support  ---> Serial console (USART3) is 
correctly defined)

$ make

(flash firmware nuttx.bin in your board: you can use openocd or other tool, no 
problem)

Besides the "nsh>" another indication that NuttX is starting is a solid LED 
turning ON, if it is crashing you should see an LED blinking.

BR,

Alan
