I tried to extract Ambarella FW module from DJI firmware package, and place on SD-card. I was hoping it would break the loop. Then I got a log file like this: Cortex Boot-Up Success Cortex freq: 504000000 ARM freq: 17600000 DDR freq: 396000000 Core freq: 216000000 iDSP freq...

Based on these lines of text, can it be concluded that something is wrong with the gimbal?

Congratulations SelfBiased I set the speed to 115200 and now it works .

I tried to change the character set, only different characters appear but still not readable.

I get these lines, where am I wrong?

Like this?

Should I connect like this so I could get a log from the Ambarella chip? Where on the gimbal board should I connect the 5v power supply?

I have a problem with image transmission signal on my Phantom 3 advanced. The green LED starts flashing on my gimble board, over and over again. Could the problem be in the flex cable that connects the board and the camera? Has anyone tried whether the gimbal can start normally if it is not...

Another question. Is it possible that if the flex cables connecting the camera and the main board of the gimble are defective, it shows such symptoms? Does anyone have experience that if the flex cable is faulty then the green LED flashes and the gimble board starts up again and again?

I remembered that I did not look at the hidden log file on the sd card. These are the only two lines [00000679][01 00] Firmware upgrade finished failed (step = 3, err = 0xffffffff). [00000678][01 00] Firmware upgrade finished failed (step = 3, err = 0xffffffff). The Dji Go app shows...

No, I still don't know how to check UART logs. I'm researching but nothing for now. I hope to find a more detailed explanation somewhere. Can this video be helpful?

Uh, this is already getting complicated. Since my drone had an accident, the gimbal was damaged, the original flex cable was broken, I replaced it, but with the Chinese version from aliexpress. Could there be a problem with the cable that connects the board to the camera? Namely, when I turn on...
