I recently build TL-MR 3420 V3 firmware which was not yet supported by openwrt.
The board is very similar to V2 board but V3 is with new processor Qualcomm Atheros QCA9531.
My V3 Board specifics brief are as follows:
- Qualcomm Atheros QCA9531 650MHz
- 25Q32CS1G 4M
- Zentel A3S56D40FTP -G5 32 MiB
I started with TL-MR 3420 V2 profile.
“Target System” ⇒ “Atheros AR7xxx/AR9xxx”
“Target Profile” ⇒ “TP-LINK TL-MR3420 v2”
Build success without showing any error.
Then I tried to build from stock web based firmware upgrade but failed with error 18005 because of TP-Link genuine firmware check hash.
So, I tried with serial/tftp flash method and flashing "lede-ar71xx-generic-tl-mr3420-v2-squashfs-factory.bin" was successful . LEDE is booted checked from serial console.
Error : But when I check from serial console, ifconfig shows only lo interface. No Eth/Wan nor WLAN is up.
Tried ./etc/init.d/network reload and show error.
root@lede:/# /etc/init.d/network reload Failed to connect to the switch. Use the "list" command to see which switches are available. [ 56.975151] IPv6: ADDRCONF(NETDEV_UP): br-lan: link is not ready 'radio0' is disabled 'radio0' is disabled
Checked boot log and noticed errors.
[ 0.115999] ar71xx: invalid MDIO id 1 [ 1.414894] ag71xx ag71xx.0: invalid speed specified [ 1.420074] ag71xx: probe of ag71xx.0 failed with error -22 [ 2.014883] ag71xx ag71xx.1: invalid speed specified [ 2.020033] ag71xx: probe of ag71xx.1 failed with error -22
Seem Switch/Eth driver is failed to load. How can I add network support for my board. If someone has experience on this series, also let me know.
