P1 Pin Functions In Bootloader

I’m designing a board with the P1. I wanted to know what’s the state of all the pins while the board is in bootloader mode. A colleague of mine claims that an attached I2C device is getting toggled during programming.

Also, what’s the current draw when the board is being flashed via the bootloader?

Finally, are any pins toggled (other than the LEDs) in the default firmware?


AFAIK only some of the JTAG pins will be non-highZ during bootup since JTAG will require pull-up/pull-down resistors.
I’m not sure which pins are used as JTAG on the P1 tho’
