先試一下你的PC serial port work 唔 work,你有冇serial cable 9 pin to 9 pin to connect IP01
set your com part 8N1 baud rate 115200, once connected press return to see if anything show up in your terminal.
For the firmware, I can email to you tonight.
Be prepared that you may lose control of the IP01 because it can't boot up. But no panic, as long as you can see the boot process and message from the serial console.
