DR500GW-HD self bricked?
« : 05 Ноября 2014, 13:57:48 »
Hello guys, greetings from Slovakia  ~))

I am dealing some problem with my DR500GW-HD already discussed at dashcamtalk forum, so I`ll copy-paste some info here as I am lost in ideas how to recover it.
Link to discussion:
http://goo.gl/Iz3RdE

Issue description:
Everything was ok untill yesterday, I stopped at the petrol station and once I moved, camera repeated some some non-english sound. I guess russian. Several times I removed power cord to restart, no success.
At home I removed card, used SDformat tool, made surface scan and copied them fresh-downloaded firmware v2.002. Same software version was on SD card before.
All LED blinked once, then GPS (blue) LED s ON for 6 seconds,
then Security LED (in front) & REC LED (in red) & WiFi LED blinked once,
REC LED (in green) keep ON for 11 seconds.
During this time there is no recording detected on microSD card.
Once started without SD card, same behavior as described above but green REC LED keeps ON untill powered.
I have tested 2 microSD cards fresh formated to FAT32:
- 16GB MicroSDHC from Pittasoft
- 64GB MicroSDXC Kingston
Car voltage checked, it gives me 11,89V DC, at home I use 12V/1,5A; 12V/5A and 12V/300mA power supplies.
Several monkey-snatch tried with reset and WiFi button, no success too.
Battery was changed 2 months ago, I have tried to install firmware v1.005E on SD card, but no success, it just ignore SDcard.
I guess I will need to use some UART cable..
Or is there any way for deeper troubleshooting?
I am open to all possible options to recover my only dashcam.
May I kindly ask you for guidance please?

Thank you in advance for your advices.

OK so, I need UART cable at the first. Would this be applicable?: http://goo.gl/1d8kBx
 ..--.. Is there any procedure/guide how to push the firmware there?
Thanks in advance for your advices.

Yes

Человек делает выбор, мы делаем вывод!
Восстановление регистраторов BlackVue через UART.

Thanks for reply, I ordered it already. Delivery will take some time...
So if I want to push custom firmware from http://goo.gl/DRvKKG, how to connect UART (pins) and which file to push to DR500GW-HD?

 )ooo( Great, thank you guys, Gtranslator gave me text in english so I can go on once I receive UART  )ooo(
Based on picture from Delorm`s first post of mentioned topic, I should connect to 16PIN slim connector.
Guess I can write down some steps in english afterwards...  |||

Hello guys,

I have just received UART and cannot wait so I connected cables, installed driver for UART, started dashcam without SD, holding "d" while I got a prompt:
DR500GW-HD>loadb 0x82000000
I have pushed file "cramfsImage_DR500GW" (from DR500GW-HD_v2.002E) over HyperTerminal which took some time..
DR500GW-HD>nand erase 0xa00000 0xdd0000
DR500GW-HD>nand write 0x82000000 0xa00000 0xdd0000
...reboot, no WiFi detected, no alarm from dashcam...
Welcome to MontaVista(R) Linux(R) Professional Edition 5.0.0 (0702774).
console login root/pt
Inserted SD with patch_DR500GW.bin at root
# cd /
# mount -t vfat /dev/mmcblk0p1 /mnt/mmc
# rm -rf /mnt/nand/*
# tar -xvzf /mnt/mmc/patch_DR500GW.bin -C /

Any guru's idea please? Thx in advance.

I am not sure about following:
DR500GW-HD>loadb 0x82000000
DR500GW-HD>nand erase 0xa00000 0xdd0000
DR500GW-HD>nand write 0x82000000 0xa00000 0xdd0000

Any advice please?  ))O((

it gives me an error:

After I send a file via HyperTerminal, it gives me this output:
## Total Size      = 0x00b99000 = 12161024 Bytes
## Start Addr      = 0x82000000
DR500GW-HD>
I just cannot do anything with /mnt/nand as it is read-only filesystem
