Imxrt 1050

[Embedded Systems <iv...@gmail.com>]

Hello

I wish to ask for little bti help. I updated my nuttx to the latest version
since i want to update my work with the latest Nuttx version, because i
will resume working on drivers for Imxrt1050, but i am facing a strange
problem when i tried the new Nuttx builded the imxrt1050-evk:nsh
uploaded the firmware everything is working properly but i cannot flash new
firmware if i do not switch the board in Serial downloader. Previously i
didnt need to switch the board in Serial downloader mdoe in order to flash
firmware . Any idea is there something changed on the SWD debug is it
disabled?

Thank you in advance
Best regards,
Ivan ucherdzhiev

Ivan,

This does not happen when programming imxrt in other environments (e.g. 
Zephyr, FreeRTOS) and is a concern to me since it implies there's a 
clock not switched on properly somewhere. We had this problem with the 
tick timer not interrupting when WFI was first (re-)enabled but that one 
was fixed. Chances are there's another bit hidden in one of the GPR 
registers controlling this. I'm back now so will investigate...just 2000 
emails to catch up with first.

Regards

DAVE
