Problem uploasing esphome firmware to KC868-A16

[tolbier]

Hello:
I've got two KC868-A16 and now I'm trying to upload the firmware, but it replies me with an error on Erasing:


It keeps for a Long time and it returns a TimeOut error

Also, I've been trying with the ESP_FLASHER tool with similar result:


I tried with both cards and, the result is the same 
Also I've been trying to upload it pushing Reset and Download Buttons, with no different result

I was trying tou upload from a Fedora 39 and also from a MacOS (Silicon M3)

any idea what is going on?

Thank you
