wcc ends in panic:timeout

[jwiggers]

LS,

I am trying to flash lua rtos with wcc to my nodemcu esp8266 and get the following results. This is from MacOs but i get exactly the same results on windows. What am i doing wrong?

Hi @jwiggers you need to replace SLAB_USBtoUART by your actual USB enumeration name.

You may use the -ports parameter to wcc:
./wcc -ports
as this will show you a list of available usb devices.

Other users of MacOS seem to have names like the following, just as an example:
./wcc -p /dev/cu.usbserial-FTYKHBJT -f -ffs -d
