With the SD card, I'll try again
how did you compile the firmware?

I'm trying firmware_ The latest firmware in binaries
so you went to http://RatOS.local/configure?step=1 followed the steps? Clicked the "compile firmware" button and then followed all the steps written out below?

yes
what is the output of
ls /dev/*
?wee-brownā¢2y ago
Yes, firmware failed to flash
The strange thing is that after re flashing, the prompt MCU cannot connect is still displayed
so it was not renamed to FIRMWARE.CUR?

After one successful change, there was no further success.
what does
ls /dev/serial/by-id/*
show?wee-brownā¢2y ago
