KC868-A16 detected but failed to download firmware - mohaz - 06-12-2025
Hi,
I recently purchased a second KC868-A16 , the first one installed ~4 months ago works fine
But the new one can't download firmware using flash download tool (see attached file)
I tried the followinf steps:
1) use the original Usb c cable , and try another one (no usb hub) same from anotehr PC -> NOK
2) using flash downlod tool with different rate -> (see attached download tool log) => NOK
3) Trying upload using esphome -> NOK (see attached error log)
4) Even connected to Lan netowrk the scan tool can't detect it
NB :
The usb device is connected when plugged but there is communication issue or flash issue.
Thank you for your support.
Regards.
