recover beagleplay

I powered on my BeaglePlay after some time. It’s in some sort of serial flasher mode, it spits out ASCII C. How can I recover it?

I want to flash a custom Yocto image to the emmc. So also want to update u-boot.

Thanks!

Using the latest Debian emmc flasher image via SD card

  • press reset and user, release reset, release user

No impact

It boots my Yocto image fine. Hmm
