Hello,

You could use memtool to see and write the registers of the i.MX.

This tool is located in the following path:

/unit_test/memtool

To use it, the clock of the module needs to be set. Otherwise, the board will crash.

An example of how to use the tool could be.

./memtool -32 0x02A30000 1

The 0x02A30000 is the IPU2_CSI0_SENS_FRM_SIZE address for the i.MX6Q.

For more information about the address of the IPU registers that you mentioned. Please see page 2903 of the i.MX6Q reference manual.

Hope this information could help you.

Best regards,

Diego.
