no booting from SDCard

Products & Technology ReSpeaker
#1

Hi,
I just received my ReSpeaker Core v2 board.
I followed instruction from the Wiki to boot from SD (and to boot from eMMC) but it does not work at all. For preparing SD cards I tried with Etcher on a Mac.

Basically when I power the board (with a SD card, prepared, or without) the result is always the same :

  • Only the Power green light is On and steady

  • On the back all (but one ; one is burned?) ring leds are steady Red

  • No activity on USR1 &USR2 LEDs ; They are Off.

Did I get a faulty board ?
Can you help to boot it please ?

Hi there,


1. Which image do you burn to SD card? We suggest respeaker-debian-9-lxqt-sd-20180801-4gb.img.xz

2. Please plug the HDMI cable and then plug the usb cable to power the board. Please check if there is any display signals.

3. If you have the usb to ttl adapter, you can connect to the #5 connector. Then you plug the adapter to PC, you use the serial com port monitor to check the output. please post the error message to us. thanks.



Thanks

best rgds
