it appears perhaps many more cam sensors are supported looking at strings on an XF16

But it looks like only for GC0308 and GC0328C sensors

are these of any use? https://github.com/adasngle/testmywatch/tree/master/custom/drv/YUV_sensor

Possibly. The most important things are initialization arrays, which they have.

Hi, the initialization table for the hi704 that I uploaded to GitHub was working. I had a working build for the BK7252 with this sensor on my previous SSD.

neat. GC0310 too. pretty nice way of finally knowing what the cams are (if ribbon print isnt clear or boot log doesn't help), assuming theyre covered by the list above.

@insmod @p.kaczmarek2

I was thinking about tracing as many of the XF16 pins as possible against known components/functions, like RX/TX, LEDs. BUT, can what been seen in XR872 currently be relied on as a correct XR872 pin number to any extent? I'm thinking maybe not yet

I think you'd probably need to add more entries here:
https://github.com/openshwprojects/OpenBK7231T_App/blob/main/src/hal/xr809/hal_pins_xr809.c
Check respective SDKs for what may be present and then check each pin one by one:
Code: C / C++
Log in, to see the code

Check here:
https://github.com/openshwprojects/OpenXR872/...343b51ba9/include/driver/chip/hal_gpio.h#L657
There may be also port C:
Code: C / C++
Log in, to see the code

Code: text Expand Select all Copy to clipboard
ifeq ($(__CONFIG_CHIP_TYPE), xr872) __CONFIG_CHIP_ARCH_VER := 2 __CONFIG_CHIP_XR872 := y ifeq ($(__CONFIG_CHIP_TYPE), xr808) __CONFIG_CHIP_ARCH_VER := 2 __CONFIG_CHIP_XR808 := y CONFIG_SYMBOLS += -D__CONFIG_CHIP_ARCH_VER=$(__CONFIG_CHIP_ARCH_VER) ifndef __CONFIG_CHIP_ARCH_VER

I am creating multiplatform open source firmware (Tasmota replacement), right now supporting BK7231T, BK7231N, XR809, BL602, W800, W600, LN882H and soon supporting RTL and W701:

gosh, thank you for taking the time to point these bits out. I'll try to get my head round what's required when I have a moment to focus

This seems to mean that there are at most:
Code: text Expand Select all Copy to clipboard
#define GPIOA_PIN_NUM 24 #define GPIOB_PIN_NUM 22 #define GPIOC_PIN_NUM 13

24+22+13 pins to check, but usually not all are routed out on the case.

You're getting XR809 and XR806 build errors because port C seems to be present only on XR872.

Code: C / C++
Log in, to see the code

Probably just need to take PORTC pins into the #if PLATFORM_XR872 block

Ah ok. Thanks. It also looks like this in gui so I'm missing something else too. Need to get back to looking at it

There is also PLATFORM_GPIO_MAX in new_pins.h
