Hi all, I’m using an FDP-LINK III cameras with TI serdes pair, i need to retreive the intrinsic parameters from the camera In the past i used a camera module with i2c eeprom, all i needed to access and hexdump the eeprom is to add the at24 device tree node in the right i2c bus. I want to do the s…

Only if the SPI able to pass the SPI command to flash via I2C command.

Have a reference to below SPI relative topic for Xavier. Thanks [image] NVIDIA Jetson AGX Xavier GPIO Header Pinout - JetsonHacks The Jetson AGX Xavier GPIO Header Pinout Table. Est. reading time: 4 minutes [image] How to u…

Hi @ShaneCCC I mean how to know in which spi bus will be detected the flash spi ? I am not using directly the jetson pins, i am using cam_i2c port to use the camera module that has an spi flash memory. Is there any example about how to know if the spi flash is detected ? Thanks

Looks like the flash is connect to the external ISP chip. The only way to communicate to the flash is from external ISP. Please consult to the vendor I don’t think Jetson able to do it.

@ShaneCCC i used a camera with an i2c eeprom, i was able to use at24.c linux driver to use it in fact i had the access through i2c but to its address (0x50), there is no possibility to do the same thing for this spi flash ?
