I think I tried 1.99 (for 4MB) and had the same issue. Let me get back to it once I have some time again to spend on this. Perhaps there was something I missed in those tests. It was a lot of combinations in a single weekend.

No, it is not. I was too optimistic when I was able to connect to it.
The
wifi.connect()call consistently crashes it.@MaBe I haven't looked into these addressing specifics before. I have tried flashing it as 1MB/2MB and 4MB boards and none of those seemed to help.
Any suggestions?

The fact that the Tasmota firmware works without any issues makes me think about what Espruino needs changing to support these particular ESP8266s as well.

It's from here
https://www.aliexpress.com/item/32662942091.html?spm=a2g0s.9042311.0.0.5e184c4dZPSXYsBut the boards I got don't seem to be WAVGAT nor AI Thinker modules.

The Tasmota MQTT firmware works without any issues on the same board with the following flash command
esptool.py --port /dev/tty.wchusbserialfd12240 write_flash -fs 1MB -fm dout 0x0 tasmota.binSo it looks like it's not the board part itself.

It is still not usable completely...
I get less garbage with 80MHz SPI Speed. But the serial connection drops after a while for no apparent reason... It behaves similarly with 20MHz.
wifi.connect() makes it disconnect and not possible to connect anymore.
It almost looks like some kind of thermal watchdog resetting after a while. It is fairly warm when I touch it in just a few seconds of plugging in.

This separate files doesn't seem to work properly in my case. Both with previous flash erasure. What could be the reasons for that?
esptool.py --port /dev/tty.wchusbserialfd12240 write_flash -fs 4MB-c1 -fm dio 0x0000 boot_v1.6.bin 0x1000 espruino_esp8266_user1.bin 0x3FC000 esp_init_data_default.bin 0x3FE000 blank.binBoth of the flash command lines result in (when connecting on 74880-8-N-1)
