Hello my friends. I would love to discuss the possibility of understanding the nature of ARM programming when it comes to Marvel series controllers and data recovery. What added benefits one can have by knowing ARM in the field of DR.

I don't know about WD/Marvel, but learning ARM has been helpful for analyzing Samsung SSD firmware to me:

If you want to learn ARM, perhaps it helps you to take a look at the ARM code and my comments in the traces I collected:

So good to see all this. So far I am starting off with ARM CORTEX M4 and taking small steps.
Right now I am trying to build a DSP based OPAMP analyser as a DIY project on CYPRESS FM4.
This is solely to do Transfer function analysis etc for various 2 port networks that I design and after establishing the Impulse Response, trying to digitize it aswell.

So far going forward, then will go reverse :D
