@siderat I think this one will work.

1_ Writing 0xff to 0x000b solved our problem and now the CSI-2 output of the module is in HS mode not LP mode. Thank you. Please give us a command to save this change.

Sorry, this command cannot save settings during a power outage.

2_ We are trying to change video frame rate (now is 30fps and we need 25fps).
by these commands we cannot do this :
0x10 0xDE
0x11 0xC2
0x12 0x00
0x13 0x00
(sending Two byte, then sending next two byte and ... ).

write_videoformat() { local videoformat=0; local res=0; res=$(./i2c_write $I2C_DEV $I2C_ADDR 0x10 0xDE ); res=$(./i2c_write $I2C_DEV $I2C_ADDR 0x11 0xC2 ); if [ $PARAM1 = "PAL" ] ; then res=$(./i2c_write $I2C_DEV $I2C_ADDR 0x12 0x0); elif [ $PARAM1 = "NTSC" ] ; then res=$(./i2c_write $I2C_DEV $I2C_ADDR 0x12 0x1); fi res=$(./i2c_write $I2C_DEV $I2C_ADDR 0x13 0x00 ); printf "w videoformat is %s\n" $PARAM1; }

The detailed code of the i2c_write function in the above example shows the actual bytecode it sends. Specifically, i2c_write sends multiple bytes in a single standard I2C transaction to modify register values.The specific steps are the same as writing 0xff to 0x000b.

@lpcq2000 抱歉现在MCU bypass模式已经不再被支持了。我们的资料有一些迟滞，回头会更新到上面。

Only ISP-related parameters can be persistently saved after power-off through the paramsave command. Therefore, I recommend that you reconfigure your desired parameters in the startup script during program design.

As for which commands can be saved, you can refer to the veye_mipi_i2c.sh source code. If the corresponding read/write functions contain operations like './i2c_write $I2C_DEV $I2C_ADDR 0x10 0xDA', it indicates that the function's register belongs to the ISP category and can be saved using paramsave.
