I traced the chip pins to the outer pins. This is what i got:
I guessed a little and it seems to be the same as this one:
So i pulled A0 and CEN to 3,3V. Now i get this message:
== Rtl8710c IoT Platform ==
Chip VID: 5, Ver: 3
ROM Version: v3.0
Test Mode: boot_cfg1=0x20
Download Image over UART2[tx=16,rx=15] baud=115200
I am already communication via pins 16 and 15. Do you have any idea how to dump the firmware? Or what firmware i could flash?
Try ltchiptool, it can dump and flash firmware of the chip. A ROM dump could be useful if you can share it.
As for firmware, LibreTiny has preliminary support for RTL8720C. Things like OTA are not implemented yet.
I am a little bit confused, because my device reports as Rtl8710c IoT Platform == ... is it different from RTL8720C ?
No success yet with dumping.
No, it's fundamentally the same thing. 8710 is the generic family name, also 8710 is a version of 8720 without Bluetooth. What matters is the "C" after the number.
I desoldered the Wifi module from a Gosund EP2. I managed to hook it up and It talks to me via UART. But i have no idea how to put it into download mode and what kind of firmware i need.
This is the comm PCB: Front with W701 chip![DSCF1030](https://github.com/libretiny-eu/libretiny/assets/72879802/13db31a9-3588-4d77-82ca-76abf41b0290)

I hooked it up like this:![Communication](https://github.com/libretiny-eu/libretiny/assets/72879802/56ba8441-0532-4b39-bd0f-670cc53a7d74)
