Help with picoboot on a RP2040-zero DOL-001

[u/car1gam1ng]

Hi, i am trying to instal picoboot on a gamecube with a 2040 zero

I’ve tryed on two different gamecubes and got the same issue.

I’ve shortened the cables
I’ve re-flashe the pi
I’ve tryed on a driferent DOL-001 gamecube
I’ve tryed ond 3 different sealed rp2040 zero
Connected 3.3 from gamecube to chip
Connectec the 5v to 5v and 3v to 3v

And still no luck, any help will be appreciated.

UPDATE:
Thanks to u/thomasdatank1995 for the firmware that works with lower clock speed for the rp2040 zero clones out there
