| If you don't want to get error (40) because of boot 2, when you do a write select a boot 2 file for your device in 'system\write_boot_64bit'
DO NOT use test strips (ribbon), they add a 1.5 resistance and that might be why the error 40.
I have tested this 100%
Use a very low temp solder paste to reball so is easy to remove, if everything works out fine then re-ball with high temp solder paste. |
