I’m trying to flash the eWeLink PCIe Computer Remote (SANT-SUD01) as detailed here.
My Pi running Home Assistant OS & ESPHome has insufficient memory to successfully compile so I have to compile and run on a WSL Ubuntu machine. However it is successfully identified & Backed Up the chip and stock firmware and am using the USB to UART Module (Micro/Mini/Type-A or Type-C) | The Pi Hut module to connect to it.
When flashing it usually fails at 50% - is there an undocumented stage that’s required first or should this be working?
Also tried directly from python on Windows and get the same error.
