Recently, ESPhome added support for BK7238 chips and I tried to flash the chip. The firmware failed and now with the native VK7238 firmware using BK7231GUIFlashTool, a message appears:
0x00...CheckRespond_FlashWrite4K: bad value returned?
0x1000... Writing sector 0x1000 failed!
Writing file data to chip failed.
Can this be fixed?
What is the exact device brand/model and the exact chip/module marking on the board? Is it definitely BK7238 and not BK7231N/T or another variant?
BK7238
What exact flashing steps/settings did you use: BK7231GUIFlashTool version, firmware file/source, baud rate, UART adapter voltage, wiring, power supply method, and whether you made a full flash backup before flashing?
Everything is standard, I've flashed it many times already.
