P4P GIMBAL 2
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.
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? Photos of boards within the drones? Ability to download firmwares from micro-controllers? Other?
Yes, I have the disassembly skills, and I have decrypted and got the firmware of the chip. I have a lot of UAVs to test.
Here's a simplified Ph3 schematic; ph4 is similar in concept: https://github.com/o-gs/dji-hardware-schematics/blob/master/phantom_3_pro_overview/phantom_3_pro_overview.pdf
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.
I got the firmware of the microprocessor, and I could rewrite the firmware into the microprocessor.
If you prefer a chat-style communication, you can find me on Slack. Invite is here: dji.retroroms.info
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: https://join.slack.com/t/dji-rev/shared_invite/enQtMjk5OTEyMzcyMjI3LTdlZjY4NzQ5M2M2NmE5ZWM4OTgyNThmZDVmZjdjODE4ODYyNmYwZjYxMDcyYzcxNmZlYzI5ZjI2ZGQ2NGY1ZTc
I'm not using any other chats. For private communication, just email me.
I have Y R ESC schematics and FW, but I don't want these resources to appear on public platforms, so I want to go to other platforms to communicate.
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.
Eu tenho esquemas YR ESC e FW, mas não quero que esses recursos apareçam em plataformas públicas, então quero ir para outras plataformas para se comunicar.
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.
Peguei o firmware do microprocessador e pude reescrever o firmware no microprocessador.

Hi, how to read& write binary files in p4p IMU board &yaw motor drive board chips? I have usb to ttl convertor. Which software to use read&write binary files. Any other tools for programming? Please help. I will ready to pay. Thanks. WhatsApp- +919842193180.
他们都是处于加密状态 无法读取 通过特殊手段对芯片开片才可以得到

how to read& write binary files in p4p IMU board &yaw motor drive board chips? I have usb to ttl convertor. Which software to use read&write binary files.
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?
I already have all these data, and I have made them tools and calibrated them.
The attached picture is the calibration software I developed.

Hello, fengzhonggeinichengnuo how can i contact you? I have the interest into buy the solution to calibrate the phantom 4 pro gimbals
Como você disse antes, ao contrário do Spark, o P4P não parece calibrar ativamente, o que pode ser muito difícil.
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
