Could you help me find the right image please? (XTDP-LINK PL-AP501s)


I have had an old DIR-615 that has been stuck in LEDE 17.01.4 for as long as the development stopped for the hardware.

I would like to change it for a new unnamed access point I found that is based on the MT7620A chip, it has 512Mb (64MB) DDR2 SDRAM ( NT5TU32M16DG), 64Mb (8MB) of serial flash (MX25L6406E), has 2 eth ports (going to the SoC) with no external switch.

Do you know of any OpenWrt image that would be close enough to this device to work? I'm looking for a premade image, I haven't compiled anything with an OS before (only microcontrollers). I took some info from the original OS, it's a Chinese AP, but it has telnet:

I don't know if it's relevant, please tell me if you want to know more commands or chip numbers. I was also wondering if there was a way to take an image of the original software before modifying it, and what is the best way to flash it, the utility on the Chinese webpage or some tftp/telnet command, or a TTL to USB. Please let me know, thanks!

Development on a new device is usually based on network booting initramfs images using a TFTP server and serial commands to the bootloader. This doesn't affect anything in flash. To run from flash will need to determine the flash partitioning and match it.

There is nothing written anywhere on the case, no OEM, no Model number, not on the front, not on the back, just a blank white case?

PL-AP501s (seems to be made by XTDP-LINK) and The top cover is blank

I would rather run OpenWrt than the generic Chinese OS that was last updated in 2015.
I can give you more info if you wish Thanks for your help!

Can someone point me to a tutorial on how to make an image with all this info?

Sorry, there are no pretty picture, videos or shortcuts.
