Hello,

I am looking for recommendations for example Jlink script / JFlash script files that could be used for starting points to be capable of reprogramming the NXP IMX6ULL's EVK's QSPI NOR Flash.

The IMX6ULL EVK uses a Micron 32Megabytes QSPI Nor Flash. According to the schematic, it is part number... N25Q256A13EF840

According to Segger's James Murphy... youtu.be/avGTK4rKpZY?list=PLDqLs4CjhqjEPT3ltdY7W4Sa8aWfL9-4G

...we should be able to start with an existing JLink/JFlash script file and modify it, to make it work with the specific memory we are trying to program.

Any pointers as to 'which?' example script file it would make sense to use as a baseline for JFlashSpi reprogramming of the Micron N25Q256A13EF840 installed on the IMX6ULL EVK?


I have installed recently released JLink_V620c, and have found there are not very many JFlashSpi example script files to choose from...

Thoughts?

Thanks much in advance!

Hi Niklas,

I apologize for not realizing JFlashSpi is not the Segger Utility I should be working with. Explains a ton.

I tried JFlash, and observed it auto-detects the 32megabytes Nor Flash straight away.

Read / Re-program works out-of-the-box (as you proposed).

Appreciate it sir!
