I appear to have solved the issue, I’ll try to outline the steps I took it might help someone else out.
Using the Linux CLI tool (Current as of Sep 25, 2020 amebad_flash_tool_v0.1.0_linux, and core version 20200730-rtl8720d-images-v2.2.0.2)
I was watching the directory while I was issuing commands with the tool, why was I doing this? well…I have no good reason, but what I noticed was when I issued the erase command, I would get a copy of the 3 bin files (km0_boot_all.bin, km0_km4_image2.bin, and km4_boot_all.bin), these were about 2.1m total.
I looked in unzipped directory containing the new core, and noticed that those were also 2.1m total. I thought, ok, that seems strange.
So I looked in the original zip file, and the total file size was closer to 836k, at that point, I figured that the erase command, copied the contents of device to the directory, and the flash command copied those files to the original unzip directory.
So to test that theory out,
I deleted the km0_boot_all.bin, km0_km4_image2.bin, km4_boot_all.bin from from the “amebad_flash” directory. Again I issued the erase command, and again I got the three files with a total of 2.1mb
I deleted them again, and copied the original 836k into the directory. I also copied the original 836k files into the 20200730-rtl8720d-images-v2.2.0.2 directory.
I issued the flash command, and then put the wifi_scanner sketch on the device. It worked
and I tried a couple of sketches that used WIFI, they worked.
So, I suspect that the flash command is coping the 2.1mb files over the 836k files, and the 836k files are the ones that are needed… And not the other way around, which is what I suspect is suppose to happen.
I hope this makes some since.
