No, no time. Sorry. |

Hi My Idol mefistotelis |
|
mefistotelis My Idol Can I help you |
Sure, any help on the gimbal is appreciated. I am not working on this yet, though I'm planning to get back to it. What can you do? Do you have repair skills, or disassembly skills? |
|
Here's a simplified Ph3 schematic; ph4 is similar in concept: Gimbal is controlled by STM32 uC, but each arm has its own dsPIC uC. We have firmware of the STM32 (without loader; would be nice to have it too, but it's not mandatory for the subject). But we don't have firmware of the dsPIC. You could check if the FW is protected or whether it can be dumped. |
|
Ok then, can you get the firmware from dsPICs for us? |
|
If you prefer a chat-style communication, you can find me on Slack. Invite is here: |
|
I can't open this website. Maybe it's due to regional restrictions. What other ways can I keep talking? |
|
Here's the current link: I'm not using any other chats. For private communication, just email me. |
|
As you said before, unlike Spark, P4P does not seem to calibrate actively, which can be very difficult. |
|
Then it would be best to send those via e-mail, either as attachment or links to any upload service. |
Can you share it in private? I'm also at the same goal of getting this. I have good experience in testing... Soon, we'll be able to uncover that mystery. |
Olha amigo vc poderia vende as informações para calibra o gimbal P4 p4pro?? WhatsApp +558199133-0291 Brasil |
I have interest. Can you contact me? +55519999483379 or guewald@gmail.com |
Your WeChat, please? |
hello friend you can talk to me by email. suporte@tecdrone.com.br |

Hi friend

Hi, |
IMU board - that's STM32 processor, so you should use STM32 programmer. You won't be able to read the chip though, because it's protected. Thew firmware probably consists of bootrom part and application part, and only application part is included in FW updates; so reflashing this chip would require dumping bootrom using hacked application part, and then appending proper application part to that bootrom. motor driver board - the CPU is rebranded as "DJI", but it's just normal uC. We'd have to know the real model of that uC to tap to it. finally - can you please also photograph the other side of the IMU board? |

Hi, thanks for your support.

Only software? Including any tools? Which models compatible? Only for gimbal calibration? Please send full details.

Hello, fengzhonggeinichengnuo how can i contact you? I have the interest into buy the solution to calibrate the phantom 4 pro gimbals |
Hello we could talk by wechat about the phantom 4 my name is Lucas Bacciotti on wechat |

@mefistotelis I am also interested in helping with gimbal recalibration, had to swap the yaw motor out of a p4p as the drone was crashed, also the esc board for yaw was missing, but it seems a salvaged board from a p4s does work, but as expected the motor calibration is all wrong. One thing I'm uncertain on is does the IMU board store the magnetization data, or is it stored on the esc boards? I have 1 working p4s and the p4p with faulty yaw calibration that I can contribute with as needed From what I understand if the IMU stores this data, then you could swap the magnet from one motor to another to retain calibration. But if it is the esc board then I might be screwed as I have no idea where the original one is, and only have access to a spare one from a salvage drone. I'd rather help find a software fix than resort to magnet swapping |

I also have a zenmuse x3 to help improve the service script. Thus far I got as far as loading the elf binary into iaito for decompiling, but have had no luck sourcing ambarella documentation to convert the assembly into something human readable |

Thanks for answering me, would you have the file to do the recording of
stm32.?

Hello, I have been looking for you in the question section some time ago. Do you have time to do the P4P gimbal test recently? I can pay for it.
