BL602 Factory firmware backup before flashing OpenBK #680

Open ataa opened 1 year ago

ataa commented 1 year ago

I have some BL602 based RGBCW bulbs, flashed some of them successfully but a some their features (Bluetooth remote control, ...) lost as yet to be implemented in this firmware. Is there a way to dump/backup the factory firmware before flashing this firmware. I have BLDevCube but couldn't find any way to backup the firmware.

openshwprojects commented 1 year ago

Hello, accordinng to my knowledge there is no way to do this in BLDevCube, but I may be wrong.

ataa commented 1 year ago

After many unsuccessful attempts, I managed to dump the flash using blflash, using the command below, but I am not sure if I did it correctly, The part I am not sure about is the ending address.

blflash-windows-amd64.exe dump BL602-Lamp.bin -b 230400 --port COM3 0 0x200000

openshwprojects commented 1 year ago

Wow, nice, this is very useful. Can you submit it in form of a short tutorial/topic to our Tutorials section? https://www.elektroda.com/rtvforum/forum517.html Give a proper title to topic, write short description how to do that, etc, where to get blflash Thanks!

ataa commented 1 year ago

Sure, I'll do that as soon as I make sure I did it right, the ending address is correct and the dumped firmware is valid. Do you know the BL602 flash ending address? or a way to check the dumped flash validity? I found 0x200000 end address in blfash repo.

I don't know, but... if you launch flasher from our SDK: image You get reference to: W:\GIT\OpenBL602\tools\flash_tool\bl602\partition\partition_cfg_2M.toml and that file contains:

Latest BLDevCube is 1.8.2 which looks different than your screenshot and there are changes in tabs, filenames and partition table. After running it and selecting that partition cfg, I get Warning: This v1 partition table is deprecated.

To test if the dumped flash is valid, I flashed your firmware on BL602, then flash the factory one again to check if the dumped flash is valid and working as expected. I'll report back.

Edit: Didn't work, while flashing was successful, I got [WARN blflash::flasher] sha256 not match and it didn't boot!

But does OBK boot correctly?

Sso far I've been using the older version of BLDevCube. I am not aware yet how to use the newest version, it seems that Bouffalo Lab has changed something in their partitions standard. It requires more investigation.

If you flash device with OBK, and then read back binary, are the files same?

Maybe binary for flashing needs to be prefixed with a certain header?

ataa commented 1 year ago

I tested it and it does work on mine, but it may not be the case for recent chips with new partition table. Also please use newer version in the upcoming video tutorials as the newer version of BLDevCube has new UI and different tabs (IoT, MCU, MFG).

bldevcube

openshwprojects commented 1 year ago

Wait, my BL602 knowledge is very small, so the new BLDevCube works on older chips if you use older TOML (older partition table)?

That's good to know. We already have recorded the BL602 Magic Strip tutorial on older DevCube, but I will try to check out the new version soon.

ataa commented 1 year ago

Yes, I tested it for BL-M5 V1.2 Board on ZJ-PWH-RGBWW-L2 V1.1 Bulb and flashed the latest release of your firmware successfully.

Hello, is the [WARN blflash::flasher] sha256 not match issue resolved?

Btw, do you know how to reset BL602 efuse to factory settings?

ataa commented 1 year ago
ataa commented 1 year ago

Good News! Reprogramed CP2102 for 2000000 baudrate and reflashed factory firmware using Latest BLDevCube and it was a success. Everything works as expected even the Bluetooth remote for BL602 Bulbs. Now I have to figure out a way to make an OTA flash out of it. It would be nice if you can add a section to your forum for sharing factory firmwares. (For research purposes OFC)

openshwprojects commented 1 year ago

That's great, what was exactly the steps you've taken to do a read and then backup restore?

Hmmm I think you can just attach factory firmware to the teardown article, we have our own attachment (and images) hosting on Elektroda.

Also, I am currently having an issue with my BL602 dev board - I tried to change mac and supposedly I overwrote efuse and it does not connect to wifi even after full erase of flash. Maybe your dump could help me recover my device.

bldevcube-reflash-factory

I have two factory images:

dump.zip Bl602Lamp-4th.zip

openshwprojects commented 1 year ago

From which exactly devices are those firmwares and how to pair them with (which app?) for testing purposes?

ataa commented 1 year ago
openshwprojects commented 1 year ago

After flashing Bl602Lamp-4th.zip, should I get anything on UART, like a log output?

ataa commented 1 year ago

Yes, it will output board model name every few seconds.

openshwprojects commented 1 year ago

Well, it's not working for me. Not in 1.4.0 BldevCube and not in the 1.8.0.

Console doesn't print anything after I repower the module into the run mode. With Chip Erase = True: image

Witch Chip Erase = False; image

nothing: image

ataa commented 1 year ago

does it activate Wifi AP after removing boot pin connection and power cycle? AP SSID should start with LEDnet00

openshwprojects commented 1 year ago

No AP at all.

It only shows AP when I flash OpenBL602 build by the old method with old dev cube like in my guide, but the AP is not functional after I supposedly broke refuse (AP shows up but my PC is unable to connect to it). I was playing with MAC address change and it's like that since I used EF_Ctrl_Write_MAC_Address_Opt function. The device on OpenBL602 works, but my PC fails to connect to it's AP, and when it's in client mode, the device fails to get DHCP IP from my Router (even though it has unique MAC).

@ataa btw didn't you read flash from offset 0x0 and ain't I flashing it now to 0x2000 offset? Just a hunch...

I don't have another BL602 dev board currently and I don't know if I can recover my one and if the issue with your flash is related to my board having broken mac efuse or to something else. BUt judging from OpenBL602 behaviour, I would at least expect log output to work and AP to show up.

ataa commented 1 year ago

I have 10s of the same board at the moment and no access to other BL602 boards, If I flash OpenBK and then reflash the factory bin file using the above method, after removing boot pin connection and power cycle, factory firmware works fine, AP shows up and I get model number on the terminal.

So I am not sure if there's security feature in place to prevent you from using it on your board or not. even in that case we should at least get some error messages
