Vonet VAP11S dump (MT7620A)
Amazon is currently selling this device for $40, but in it's current state I wouldn't pay more than $10.
Vonet doesn't offer any information or firmware about this device.
I see OpenWRT supports the Vonet VAR11N-300, which is similar in functionality. The VAP11S uses a MT7620A vs a MT7620N, and has twice the ram.
I want to make this device worth what it costs. I hooked up a ch341a and dumped the firmware. I forgot how to extract the firmware, I'll probably get to it tomorrow. Here's all the information I have, and I'm hoping someone familiar with adding new devices could jump in as well.

Device
Vonet VAP11S
SoC
Mediatek MT7620A
ROM - 4MB (32Mbit)
Winbond W25Q32JVSSIQ
RAM - 64MB (512Mbit)

To forum moderator/administrator, form says 4MB limit on images, but 3.1MB and 2.1MB both gave the same file limit error.

This is below the current required 8MB storage (which will increase to 16MB with 24.xx).

The RAM is sufficient for the current version of OpenWrt, but it will not be supported in 24.xx and forward.

Therefore, this device will not be supported by OpenWrt because it does not meet the minimum hardware requirements.

Ah, ok. I knew this was junk, didn't know there was a hard limit 8mb for support. Thanks

The smallest default images currently vary between 6.5-7.5 MB, depending on the target (modern ARMv8 ones might be larger). I recently tried to build a stripped-to-the bones (no luci, no opkg, no PPPoE, no offloading, no nothing) ath79-tiny (yes, not the same target, but roughly comparable) and couldn't get it below 4.6 MB (kernel v6.1). 4 MB has been a dead end a decade ago, and became completely unsustainable half a decade ago.

Could I have stripped it down even further, probably, but the result wouldn't have been anything I would have had any use for - the recycling bin won.

Yeah I just built a stripped down one for another mt7620 the other day and it was 5.6MB. I do wonder though, there are some options in the menuconfig for LTO and remove unnecessary code that I couldn't get to work.
Maybe I'll pick up some soics and just upgrade it and do a custom build. It would be fun.
