Device unable to boot
Thanks for the insight LMM,
With all the boot tries and reflashing I did, I don't expect to have inserted the SD card every single time.
When it comes to the power supply I'm using one of the recommended power supplied. It's a 12v@3A power supply.
I'm trying to boot the device without any accessory attached, so I don't think I'm actually overloading the power supply.
And I've followed the exact same tutorial to try to establish a serial connection.
I've been using the 1.5MBaud rate,
I was connecting the RX lead to the pin 8 and used the ground lead on pin 6 while keeping the TX lead disconnected to make sure I don't impede the boot process.
The serial adapter was set at 3.3v
I haven't tried to flash the SPI with UBoot yet since currently I'm waiting for the Pine support to issue a RMA so I can test if I just received a lemon.
But I still tried to see if I would get anything out of serial connection even without any SD card, and I just get the same goop as when the SD card is in.
And the emmc isn't an option since I didn't buy any emmc modules and prefer to run directly from a SD card for the time being for simplicity.
