I wondered for quite a while why I were not able to install the pico-hsm image onto my PR2350_One.
It seems the binaries are swapped:

Could you try with this version? https://github.com/polhenarejos/pico-hsm/releases/download/v6.4/pico_hsm_pico-6.4.uf2

I fixed a problem with the flash write for boards of 2MB like Pico.

Hi @polhenarejos ,

I tested it but with the same result. I have a RP2350 based Board which should run with the pico_hsm_pico build.
However it does not work, instead I still have to flash the pico2 binary for the UF2 to be detected and also in case of the pico flash tools to be loaded.

This is a Picture of the Chip I am running on:

Pico -> rp2040
Pico2 -> rp2350

Your board works with pico2 release.

Okay, I think I get the issue. I am not so familiar with the pico types (yet).

Leaving a small hint bevor closing the issue:

I [read the docs](https://www.picokeys.com/getting-started/#:~:text=Finder%20named%20RPI%2DRP2%20(for%20RP2040%20boards)%20or%20RP2350%20(for%20RP2350%20boards) and I was very sure that the 2350 will need the pico uf2. Maybe that could be refined a bit to be clearer.

Thanks for the support and sorry for wasting our time :D

It's a bit confusing. The mounted unit for RP2040 is called RP2 and for RP2350 is RP2350. This name cannot be changed since it's hardcoded in the bootloader, but I'll put a clarification.
