AWR6843AOP: AWR6843AOP ROM bootloader question

Part Number: AWR6843AOP
Other Parts Discussed in Thread: UNIFLASH

Tool/software:

Hello team,

I'm curious if ROM bootloader could load META IMG2 alternatively when META IMG1 is corrupted.

When looking application note(mmWave xWR1xxx/xWR6xxx Bootloader Flow), there is below description of 'Fallback images'.

Also, when looking below E2E thread, there is below comments.

https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1343473/iwrl6432-rbl-fallback-scheme-if-image-is-corrupted/5157539?tisearch=e2e-sitesearch&keymatch=fallback#5157539

Here are my quesitons.

1. Does 'Fallback feature' mean "If METAIMAGE1 boot image fails, it does indeed continue through images 2 and 3 and so on,"?

2. Does AWR6843AOP has the Fallback feature?

3. Can you please provide some examples when the boot fails? Maybe QSPI communication error / CRC check error / etc?

Your help would be appreciated.

Regards,

Hi Victor,

1. Yes fallback feature means it will attempt image 2 (and then 3 and 4) if image 1 boot fails.

2. Yes AWR6843AOP will have this same behavior.

3. Yes, QSPI error or CRC check error would be examples. CRC check would fail if some part of Flash had become corrupted. Power supply interrupt to either Flash chip or AWR device during this transaction could also cause a fail. Essentially, these are low probability events.

Tim

Hello Tim,

Thanks for reply! As far as I understand, normally we can upload one TI APPIMAGE through UNIFLASH. How can we add more app images?

Hi Victor,

We should be able to load multiple images through Uniflash tool.
