Developing Custom Firmware
For the Jetson Orin Nano
Flashing
Notes: - Current Design constraints:
- Based off of the availability of parts in JLCPCB. Possibility of parts not being found or existing. -
- Flashing is done with the flash.sh script through the following command
$ sudo ./flash.sh <board> <rootdev> where board is the actual board (Jetson-Nano-XX, etc.)
rootdev determines what type of device is being flahed. Use mmcblk0pc1 to flash a local storage device (eMMC or SD card) - TO begin flashing, put the device into force recovery mode and then press reset. - Run the flash script using the previous command specified.
Flash using a convenient script: - To avoid having to specify the rootdev andthe board configurations, can use the custom flashing script:
-
Using GPIO Pins to program protocol: - you can use the rasberry pi libraries to interface with the pins, configuring them to whatever layout that is needed.
- Example: it is possible to direclty interface with the i2c system in the nano by using the linux terminal itself.
