Zynthian booting from sd card in a raspberry pi 4

Hi, thanks for feedback, as i have burned several different images with Etcher on my Windows PC, and all of them worked fine, i suppose this one is also fine.

as booting doesnt show even prompt to put in a command or something else, there might be problem with pisound…do you remember the wiki link?

Just found the link : Unofficial hardware - ZynthianWiki

shit, has anybody an idea how to make it running with pisound?

just found Build with pisound and MCP23017, but how can this work?

thanks
Bernd
