That means it is the same hardware, and you should have flashed the sysupgrade.trx that got built. (shrug)
Should still be able to push a uImage and uRamdisk over serial. The images should fit in RAM fine. That would get the dongle booting, and then you could do a sysupgrade with the trx.
There is some problems in my TFTPd.so I need to soder the spi flash;
if I flash this https://openwrt.org/toh/unbranded/a5-v11 Firmware . the router runs well and it display "CHAOS CALMER" in TTL. The DHCP runs well.
When I make the Firmware from github https://github.com/DavidBuchanan314/fusee-lede . flash it into my router,
DHCP unwork . TTL display LEDE, maybe there is some error in my openwrt project.
