Adding OpenWrt support for Linksys EA7500 v2

For Developers
61

support is broken in current snapshot. I've opened an issue at openwrt bug tracker: https://bugs.openwrt.org/index.php?do=details&task_id=3603

Maybe its a general problem with ea7500v2 or its an issue with bad blocks in the nand. ea8100 image from above is working aswell.

Update:
I did some research and I guess the problem is related to the mt7621 nand driver, and not handling bad block table properly. If bad blocks exist, the driver does not read the bad block table and set the wrong offset to the partitions.

Do you have tutorial to install this XWRT from start? Also is the external USB storage working?
Thank you.

I've been running Openwrt on my router EA7500 v2 and i like the acquired functionalities with the firmware. However, performance is poor over 2.4Ghz radio getting bandwidth less than 11Mbps compared to the OEM firmware where I get speeds of 54 Mbps and 5.0Ghz radio performance is better, but the radio is disabled every moment.

Has anyone update to 21.02.0? How is the performance? Thank you.

FYI - OpenWrt 21.02.0 support is available now.

Please open new topics for any remaining questions.

Thanks! :slight_smile:
