Teensy 4.1 and GD32E230F8 Bootloader

[Gnomo]

I've been working on replacing U1 for industrial MIMXRT1062CVJ5B MCU on a T4.1 board. After replacing U1 I am getting error code (10 blink) serial number - very much expected with old bootloader chip.

The boards I have are post June 2022 with "U2 replaced by GD32E230F8". I see MKL02 with bootloader preprogrammed listed on site though it is not footprint compatible with new June 2022 PCB. Is it possible to get preprogrammed GD32E230F8 so that I can perform first boot operation with new bootloader chip?

From my research in this forum it seems like if I replace the bootloader (preprogrammed) I should be able to successfully boot a new U1 IC.

Thanks

Sorry, we can't offer preprogrammed GD32E230F8 chips. There's no ZIF socket which fits that chip.

Thanks for the quick response Paul, Too bad about the GD32E230F8. Is it possible to get a Teensy 4.1 with MKL02 bootloader IC from PJRC at this point? Or has the PCB footprint been permanently updated to new rev?
