About memtool support

matsumoto2 — Mon, 13 Mar 2023 00:50:35 GMT

hello
I am using SC2310H to output data to MIPI of i.MX8MP, but the data does not reach the VB2 queue.
I would like to refer to the following register values to check whether the i.MX8MP can receive MIPI data.
32E4_0020: D-PHY status register (MIPI_CSI1_DPHY_STATUS)
32EC_007C: Gasket 0 ISI Pixel Count Register

But I'm trying to use memtool but the cpu hangs when I run the command.
Does memtool support i.MX8MP?
Please tell me.

when you read these registers, did you connect any camera?

Connected to the camera of course.

I was able to confirm the target register by dumping it from the source code.
I was able to achieve my goal without using memtool.
