PiPico & Core Loader

[Manger74]

Have built the latest FPGA-Companion for PiPico.
It went well but the Core Loader does not work...
What is wrong?

[Manger74]

cmake -DBOARD=MSP20k ..

does not work...

      Board is MSP20k

CMake Error at CMakeLists.txt:35 (message):
  BOARD must be one of PICO;PICO2;WS2040ZERO;SH20KLITE;DEV20K;MSP20K

@Manger74,
MSP20K is something different than MSP20k...

Hello,
I have the mysteryshield20k_rpipico board. I modified the Tang Nano's JTAG port to connect it to the rpipico. I put the latest cores on a USB drive and connected it.
The ROMs are correctly flashed to the Tang Nano, and if I load a core (NanoMig, Atari, C64) using the EDA, everything works fine.

However, if I try to load a core from the rpipico, it doesn't work. I can select a core, but when I confirm, the Tang Nano seems to restart and load the core I initially flashed with the EDA. Are you experiencing the same symptoms?
Am I doing something wrong?

Thanks

@jmmparis maybe shutdown the BL616 by programming BL616 using flash_nano20k_unconditional.ini

[jmmparis]

@vossstef
Could I reflash the Tang Nano with the EDA if I disable BL616?

[vossstef]

@jmmparis i use the Sipeed partner firmware for FLASH programming (have some problems with my fedora openFPGA installation). No problem you could install flash_nano20k.ini and Sipeed programmer is back if you like.

@vossstef
It works, it's great!
Thank you very much

[Manger74]

@Manger74, MSP20K is something different than MSP20k...

Linux! 🤦🏼‍♂️
Thanks for the hint!
It's wrong in the readme... will fix it!

now i get this error...

[vossstef]

checkout SDK develop ynd tinyusb also develop. see discord.

found also a fix for Windows build.

[jmmparis]

Hello Vossstef,
Where can I find the information to connect to the Pico-Sdk and TinyUSB Discord servers?
thanks

[vossstef]

@jmmparis sorry but simply don't know. To my knowledge there are two github repo's: SDK and TinyUSB. Maye you will find in their readme a link. For BL616 used USB stack CherryUSB there is a discord channel.

@Manger74
I've got the same message on my old ubuntu (22.xx) distrib with an old version of arm gcc, following a message from Harbaum indicating that he was using Ubuntu 24.04, I updated my Ubuntu to 24.04 and follow the instructions to reinstall all repository to resolv this errors.

With Visual studio code on windows 10 I can compil PICO but if I try to compil MSP20K it failed.
same error as your :

The extension use arm gcc 14_2_rel1:

@jmmparis @Manger74 you need to checkout manually tinyUSB repo 'latest' develop to increase version that is used during the build
