After seeed-voicecard install, pi-image is corupt

I am trying to get the Respeaker-6-mic working on a raspberry pi 3A+



First i installed a sketch image. Did the steps which are in the wiki manual.

After the install of the seeed-voicecard. It gives no errors and says have fun with the product, but do a reboot.

I give the reboot command and than it is finished with the image. The pi doesn’t start up anymore.



Tried it also with buster image. There i get the same problem.



Don’t know what i am doing wrong. Can somebody help me?
