Netgear r7000 - Boot program checksum is invalid

After every 2nd reboot I get the following error in my uart console:
Checking crc...Boot program checksum is invalid

I can flash the firmware lede-17.01.4-bcm53xx-netgear-r7000-squashfs.chk using tftpd64.452.zip
from http://tftpd32.jounin.net/tftpd32_download.html
SHA256 checksum of the firmware file is correct.

It reports success. Also when I flash the firmware again from webUI (flash and reset). It reports success see in the log below. After the reboot - same issue:
Checking crc...Boot program checksum is invalid

Stock Netgear Firmware and DD-WRT work fine.

Anybody got an idea?

PS: wow - body limit 32000 and no txt upload?

Are you sure your tftp server is working. (Loading Failed)

I'm sure - the part you qutoed is the recovery procedure, where the router listens to 192.168.1.1 for a file from 192.168.1.2 - bascially the router acts as client here.

The actual upgrade (emergency) is done afterwards.
If you look further down, you can see the success message.
