Part Number: AM625
Other Parts Discussed in Thread: SK-AM62B-P1, SK-AM62B

Hi,

I'm trying to read CSI_RX register region by using "SK-AM62B-P1" with processor SDK ver 11.02.08.02.
Here is my example of result.
When I access CSI_RX region (ex 0x3010 0000h), I got "bus error". However when I access control "CTRL_MMR" region (ex 0x0010 0000h), I did not observe any error.

I connect "ov5640" to SK-AM62B EVM, and can access camera module (use "cam"(libcamera" app)).
So, I'm not sure why I could not access this region.
Could you please give your comment how I can access CSI_RX region ?

Best Regards,

    Hello Machida-san,

    These types of errors are commonly a result of region's interface clock not running.

    I will not be able to come back to you until early next week.

    You may try to figure out how to enable module clocks by searching the forum in the meantime.

    Thank you,

    Stan
