rgh2 jasper 512 help needed

[gixer]

Hi , i am using the j-runner to glitch a 512 jasper on 41719
did the reading part , build ecc and write ecc . also used the j-runner to program the coolrunner - now i have 4 options : A B C and D , which one should i use ? or should i try them all ? i have used B for now but i get no glitch - i got it once to glitch out of 10 boots and it took more the a minute , other options did not boot at all , only green light blinks on coolrunner . i went by the xecuter diagram , used the 10 ohm resistor and removed c15 out of the coolrunner board . has any one had better success with jasper on 41719 ?
any advice will be appreciated
thx

Start at the beginning......A then B then C then D....:wink:

Make sure you keep a clean dump of your Nand and just copy it each time you want to modify it
