BlackVue DR500GW-HD WiFi - need help
« : 19 Июля 2018, 12:29:27 »
I have problem with my DR500GW-HD. My blackvue didn't turn on when I started my car. Only blue led is on, Can't turn on/off wifi, no sound. Any solutions for this situation? When i connect via Uart i have only this:

DM36x initialization passed! TI UBL Base Version: 1.50 Boot Loader BootMode = NAND Starting NAND Copy... NAND Boot failed. Aborting...

Possible problems in the case of DVR non-start                     

1) if nothing is on, check the power supply.
2) if the blue led is lit - at least started the bootloader and possibly,
system kernel.
3) if the green led is on - the operating system of the DVR
fully or partially running, the Pittasoft applications are not running.
This may be due to problems in the firmware itself, poor quality
firmware updates, and due to damage or errors in NAND Flash
registrar's.
4) if all LEDs are lit, it is a BRICK. That is, even the bootloader does not start.

Procedures for the recovery of the recorders of the situations 2 and 3 are already fulfilled
our team, the procedure for fixing errors on the NAND flash drive Registrar
and system restore-too.

Всему свое время и не стоит его торопить !
Восстановление регистраторов BlackVue через UART.

Boot Loader BootMode = NAND Starting NAND Copy... NAND Boot failed. Aborting...
Try to solder NAND, if not help- main processor.
And if this not help- try to replace NAND. But NAND need to flashing before, or get it from another, not worked DR500 with worked NAND.

Solder NAND or processor? This is too much for me. Cam to the garbage ;)
