Thanks to the forum, now it works.
My small tutorial.
- Connect the UART cabel to J2 (antennas up, right side)
- Connect wires to UART/USB converter
. TX
. RX
. GND
O VCC - Cross TX und RX lines
- Download openwrt-23.05.0-ath79-generic-tplink_archer-d50-v1-squashfs-sysupgrade.bin
- Rename the file to openwrt-ath79-generic-tplink_archer-d50-v1-squashfs-sysupgrade.bin
- Disable Windows Firewall
- Set IP of the netinterface to 192.168.1.100
- connect router to PC
- Start Putty, check COM Port, speed 115200Baud
- Start TFTP64 as Administrator << !! Importent !!
- Set download path to file position
Power on the router, you will see may running command lines. Continus toggel a butten on your keyboard.
After some secounds you see the ath> prompt.
Add the following commands.
<<<<<<<<<<<<<<<<<<<<<<<<<
setenv ipaddr 192.168.1.1
setenv serverip 192.168.1.100
tftpboot 81000000 openwrt-ath79-generic-tplink_archer-d50-v1-squashfs-sysupgrade.bin
