[elektro] ARM SWD (Freescale Kinetis)

[Fuzesi Arnold]

Gyari demo board megy SWD -vel.
Ugyan az a proci sajat PCB-n nem megy SWD-vel.

Kapcsrajz azonos, SDWIO-n van felhuzo, nincs felhuzo, reseten van pull nincs 
pull-up semmi valtozas.

Eszkoz ID-t talal, de nem tud mit kezdeni vele.

2-bol 2 nyakon.

Letezik hogy lock-olva van a proc? IAR-ral probaltam elsore mindkettore 
ratolteni a kodot, de nem sikerult. Ennyi beverheti a lock-ot?
utana Segger Commanderrel gondoltam ranezek mit lat, de kuka. Se "unlock 
Kinetis" se "erase" nem segit.


Otlet?


Koszi!
