Support for MS2130

[matiaspl]

There's a new chip by the same vendor that is capable of 4:2:2 YUV HDMI capture over USB3 (and USB2 in MJPEG), the MS2130. Is there any chance of extending ms-tools to support that one too (provided the HID backend has been reused)? I have a capture device that uses it but it's currently not recogniized by ms-tools.

Hello,

Maybe.

Can you give me remote access to a system with this device plugged in?

What do you see when you run the current code in debug mode?

Sincerely, Bertold

Can you point me to a device with this chip I can buy?

Sure, I can do both :) https://www.aliexpress.com/item/1005004883158574.html

I'll PM you the access details.

I took a look at the firmware in the SPI flash and it seems to have the same debug interface as the other MSxxxx chips. It is extended with many more commands though.

[matiaspl]

Dumping the rom and writing it back would be a good start. The "open" firmware enables e.g. 4K low-fps capture which the "stock" doesn't have but I'd like to get back to where I started "just in case".

[BertoldVdb]

What "open" firmware do you mean? I found these two firmwares: https://github.com/YuzukiHD/YuzukiLOHCC-PRO/tree/master/Firmware https://github.com/ultrasemier/ms213x_community/tree/master/firmware

Note that it seems this chip does not use a ROM with the debug interface implementation. It seems possible to flash a firmware that will not allow further flash access. I wonder what the IC will do without valid firmware in the flash.

I bought this dongle, but it will take some time to arrive.

[matiaspl]

I was referring to the one by YuzukiHD - he mentions the 4K mode on the project page IIRC

[matiaspl]

I haven't seen the second repo, thanks for the link!

[BertoldVdb]

I have received the dongle, I will look at it on Saturday.

[BertoldVdb]

Initial support for the MS2130 was added.

Flash IO: (Note that the chip also seems to support a 64kB EEPROM for firmware storage, if this is the case use EEPROM instead of FLASH) Write: ./cli --log-level=7 write-file --verify FLASH 0 YuzukiLOHCCPro.bin Read: ./cli --log-level=7 read FLASH 0 --filename=/tmp/flash.bin

Memory regions: RAM | 65536 | IRAM | 256 | RAM.0000 EEPROM | 65536 | USERCONFIG | 48 | RAM.1FD0 SFR | 128 | B7_0 | 65536 | B7_1 | 65536 | B9 | 512 | FLASH | 65536 |

GPIO support should work as well.

[BertoldVdb]

Did it work for you?

[matiaspl]

Yes, works great. Thank you @BertoldVdb!

[BertoldVdb]

Perfect, could you email me the original firmware for the dongle (vandenbergh@bertold.org), I accidentally deleted it while implementing the flash access.

[matiaspl]

Sure! Doing it right now.
