Hi @Dave_SU
I hope that you are doing great!
Are you intending to implement and OTA , where you have a bootloader stored in flash? Or do you simply require to program an image in a production environment?
if you are looking for an OTA
We have the MCU-OTA SFW Project which supports a wide variety of RT devices , including the RT595 EVK . This project provides a secondary bootloader, with the respective application (hello world)., both can be constructed using GCC, as described on the MCU-OTA SBL and SFW User Guide
On the SDK we have evkmimxrt595_ota_bootloader, this bootloader will receive an image and communicate through blhost.
If you are looking for programming under a production environment
We have the Secure Provisioning tool , or the MCU boot utility. Which inject a Flashloader binary to the MCU. Additionally they let you add boot information to any image.
In the case you want to use a flasloader project , Segger provides one.
The flashloader is resident in SRAM and it is for a single use. You can acces to a flashloader project. See this application note Optimizing Flashloader Download Speed on RT Platform with JLink
Regarding How to compile app with GCC tools.
Could you give me more details about this ? We offer an SDK where you do not need to an IDE.
All the best,
Diego.
