Tool/software:
I would like an easier method than described here:
LP-AM243: [LP-AM243] AM2434 Firmware Upgrade Over Ethernet - Need Follow-up
Also we need to avoid the Errata Item i2331 issue.
Our board, yet to be designed, will always be in OSPI boot mode.
Will this sequence be easier than what is described in the above link and avoid the i2331 issue?
1. Our SBL will check using some persistent state method if we are booting fresh or rebooting to Full Application.
2. If booting fresh our SBL will boot our Firmware Update application that checks over the ethernet if our firmware is up to date and flash an update if necessary.
3. The Firmware Update app will set persistent state method to Full Application mode and do a warm reboot.
4. Our SBL will see from persistent state it is in Full Application mode and set this state back to fresh boot mode.
5. Our SBL will then boot our Full Application with ethernet connectivity.
We will always use these 5 steps to do a ping pong boot sequence for all of our boots using only OSPI boot mode.
Will this method work?
Thanks,
Tim S.
