When airplane designers tried to go faster than the speed of sound (a.k.a. Mach 1), they ran into problems that were so vexing somebody proposed that there was an invisible barrier preventing planes from going that fast. It turned out that the problems were that their designs were not quite strong enough to endure the forces at that speed and once they built stronger airplanes (and used plenty of thrust), going faster than Mach 1 was not that hard. There was no sound barrier.
I’m hoping the same is true as I try to upgrade my Maslow4 from version 0.77 to 1.20, but right now I seem to be hitting a barrier. I get the error “A fatal error occurred: Could not connect to an Espressif device on any of the 33 available serial ports”. I tried different USB cables and ports, but nothing seemed to work. I’m running PopOS (an Ubuntu/debian derivative). I looked up how to find serial connections and discovered that with the following command:
ls /dev/serial/by-id
I find usb-Espressif_USB_JTAG_serial_debug_unit_48:27:E2:C8:7A:A4-if00
I’m pretty sure that’s what I’m looking for, but how do I tell full-install.sh to look there?
