Hi, I made a custom Teensy 4.1 and it worked so far.
Unfortunately I killed the IMXR1062 by by a test with 5V. No problem I got 4 other boards to work with. After assembling the second custom teensy I thought of just reusing the MKL02Z32 from the first board (stupid me). I did not work, so I thought maybe I did damage the first bootloader chip so I soldered a new fresh MKL02Z32 to the same board, replacing the old one. Also not working, even though it completed the entire power up sequence. After some tinkering I finally read the "Hardware Initialization" section carefully... well, the first reused MKL02Z32 bootloader chip was not supposed to works as it was already activated on another IMXRT1062 I understand my mistake now.
But now the second one is also doing nothing despite detecting"3.3V power good" and sending the correct signal to the IMXRT1062. I do not know how the initialization is working but is the IMXRT1062 "bricked" because I installed a reused bootloader chip before?
