Hello Champs,
Deserializer 954 has been mounted.
Customer could not mount 953 and imx390 using the 9.1SDK version, he tried the following and both failed:
1. Add the following three device tree files in the source code to uEnv.txt as default
name_overlays=k3-j721e-edgeai-apps.dtbo k3-j721e-fpdlink-sk-fusion.dtbo K3-j721e-fpdlink-imx390-rcm-0-0.dtbo
Deserializer 954 is mounted, but the serializer and camera can not be recognized
2. He tried to modify the i2c address of the serializer and the sensor in k3-j721e-fpdlink-imx390-rcm-0-0.dtbo, and tried as follows:
The serializer address is assigned to the serializer in turn, depending on the address 4a~4f that can be assigned in the deserializer device tree, and the failure is recognized, but the development board can be started
Change the sensor i2c address to 0x21 from the factory. The board does not even boot, and it gets stuck and then reports an error
He also found in the forum that the imx390_serdes_config.h file defines rcm/cm and the corresponding address, etc. He also tried to modify the I2C address for rcm in the file to be 0x21, and it could not be started. An error is reported after the jam. In summary, he found that the board would not boot with an error if the camera's default address 0x1a was modified.
Thanks
Regards
Shine
