     @r @whitequark hell, even MIPS EJTAG is at least somewhat cursed

     @azonenberg @r *somewhat*?!

     i only know how to do debug entry on EJTAG 1.x/2.0 because of someone called "HairyDairyMaid a.k.a. lightbulb" which published the only copy of the code that use DMAAcc to enable PrAcc on those cores using undocumented flags

     @whitequark @r I've only worked with EJTAG 3.10 on M4K cores.

     Didn't fully implement everything but my recollection is I got to the point of being able to execute single instructions clocked in over JTAG and it worked

     @azonenberg yeah EJTAG 3 is mostly fine, you just use PrAcc and it works
