Hi,
We got problems by removing an external resistor on our hold pin. Since there is a config for the internal pull up, we remove the physical one. This ends up in holding the board in the bootloader, because we load the pin config and directly check the pin status, but to get the pin on the pull-up state needs a few ms to get on the potential.
As I see the pull-ups has a Resistance of 20-60kOhm.
I have seen @dhalbert don't get the problem as they don't use the HOLD PIN ?
regards
