brampe:

Supply the following if possible:

  • Device problem occurs on: Engenius ECB350
  • Software versions of OpenWrt/LEDE release, packages, etc. : OpenWrt 21.02. rc1 and snapshot.
  • Steps to reproduce:

When loading the initramfs image from TFTP, the memory get's filled completely.
Also, U-Boot does not react on keypresses. Tried with an older and brand-new TTL-USB adapter.

This is the serial log:
