PCB800852 FIRMWARE ?
how about this board? do you have any idea how to develop a firmware for this board?
https://ae01.alicdn.com/kf/S601617b6ba85423580d4ebbea6135bbb5.jpg
Any ideea how to force 1024x600 resolution on this board? Aparently it doesnt recognise my xyx-7di hqx 7 inch display and oupts in a distorted 800x480
Any ideea how to force 1024x600 resolution on this board? Aparently it doesnt recognise my xyx-7di hqx 7 inch display and oupts in a distorted 800x480
any updates? I'm running with the same issue
i have a stock image with a 1024x600 resolution for that board. I can upload it, if you still need it.
If you want to flash it: I couldn't find a easy access to SDA/SCL Pins so I soldered two wires to the tiny resistors (R57 and R?7 (i think ? is a "6") next to the IC-pins (right side sixth and seventh from top) and you have to add the following Flash-ID to Rova-Tool's Flash-Devices.xml:
<FlashDevice> <Description>ZB25VQ40ATIG</Description> <Signature>0x5E126013</Signature> <Size>0x40000</Size> </FlashDevice>
发邮箱给我 [email protected],还有液晶屏的型号,我发给你 Send me an email [email protected], and the model number of the LCD screen, and I will send it to you.

You can actually use DDC over HDMI for programming and reading, and this software: https://github.com/static-void/rtd266x_programmer.git
My setup is just a Linux laptop (Thinkpad X230/ArchLinux), mini-DP to HDMI adapter
First check what i2c busses do you have:
[ipdown@x230 rtd266x_programmer]$ i2cdetect -l
i2c-0 i2c i915 gmbus ssc I2C adapter
i2c-1 i2c i915 gmbus vga I2C adapter
i2c-2 i2c i915 gmbus panel I2C adapter
i2c-3 i2c i915 gmbus dpc I2C adapter
i2c-4 i2c i915 gmbus dpb I2C adapter
i2c-5 i2c i915 gmbus dpd I2C adapter
i2c-6 i2c AUX B/DP B I2C adapter
i2c-7 i2c AUX C/DP C I2C adapter
i2c-8 i2c AUX D/DP D I2C adapter
i2c-9 smbus SMBus I801 adapter at efa0 SMBus adapter
Then probe all the display ports, in my case the board responded on i2c-4, dpb:
[ipdown@x230 rtd266x_programmer]$ ./rtd_prog -d 4
I2C ready
Attempting to read chip ID...
JEDEC ID: 0x5e6013
Manufacturer Unknown
Chip: 25VQ040
Size: 512KB
Flash status register: 0x1c
[ipdown@x230 rtd266x_programmer]$
Then backup or write, as you wish. It works over VGA too, on the PCB800099 boards. Huge thanks to the author of this very versatile and great piece of software.
I have both 1024x600 and 800x480 dumps from PCB800852 board, attached here: PCB800852.zip

Is it possible to switch the PCB800852 to composite input and solder an AV lead to AV1 and GND? Would like to use this to go from composite on my retro PC to the attached 10.1" LCD. LCD is FT101DD348HD-50P

it will be much easier if you use a cheap composit2hdmi adapter or switch to PCB800099 (many firmwares, you can desolder the unused ports)
PCB800852, due to hardware reasons, AV IN is not supported

Tianyulangtong, yes, I understand, but is this because the firmware does not support it, or the input is lacking something on the hardware level? Some firmwares for the PCB800099 supports this, so if AV is routed the same, it is a matter of firmware support

Thanks for your advice. I am getting a PCB800099 and work from there 😀 If anyone gets it working for the PCB800852 then I would shift back as it seems smaller and would more easily fit in my case.
Tianyu, thank you. I will trace where AVis connected in respect to the PCB800099 board, to try to understand the difference
Somewhere at https://www.mattmillman.com/info/lcd/pcb800099/ there was/is a link to a supposedly compileable leaked source repo for these chips, that is targeted to the Keil's MCS51 toolchain, which I have. I can give it a try, and if it works, I can try to port it to the open source SDCC.
ok

Could you elaborate? I haven't traced where the AV1 goes routed on the PCB, but found somewhere a comment that this input is unused
Sorry I was only hoping this was possible, the back of my PCB800852 board says 1HDMI + 1AV. There is also an AV1 solder point with the USB power points. But it's possible it's not 'electrically' wired up like the PCB800099 is for a composite input. I was hoping it was electrically connected and only needed to have the input switched using a 'jumper' or maybe a firmware change for example.
I completed a visual trace using photos with my mobile phone. It appears AV1 is electrically connected and appears to have all of the components on the board to support a composite video input on the PCB800852 board using an RTD2660H. It is connected to pins 43 & 44 and is wired similar to the below with the same components for the AV connection. https://w.electrodragon.com/w/images/e/ee/Rtd2660.pdf However the above is using pins 45 & 46
So it is likely that board PCB800852 'could' accept a composite video in with the right firmware. Or if it has a firmware supporting AV1 then how to switch inputs??
Hopefully this uploads, shows where the AV1 terminates to the RTD2660H on the PCB800852 board. The link from AV1 to the components is on the other side of the board.
Great, thanks a lot for that. Definitely, looks like it needs proper firmware support for AV.
Does anyone knows what for is the R77?
