Other Parts Discussed in Thread: CC2564MODA, CC2564
Hi,
I have a customer who is planning to use MSP430 + CC2564MODA and implement OAD feature.
I checked below application note(APN).
http://www.ti.com/lit/an/slaa600d/slaa600d.pdf
The APN uses CC110x, but it should be possible to replace CC110x with CC2564(or any other wireless devices) by software modification.
I understood there are single image and dual image mode, but it is not clear the advantages of using dual mode.
I checked below E2E thread and understood the device always has working application with dual mode and it helps in case an error happens at OAD.
http://e2e.ti.com/support/microcontrollers/msp430/f/166/p/684816/2533626?tisearch=e2e-quicksearch&keymatch=OAD%20dual#pi320995=2
But does such error cause critical situations(deadlock, etc.) even with single mode?
As far as I understood from the APN, if OAD fails with single mode and the new application is not valid, simply Boot mode is executed next time.
Then OAD will be tried again until the new application is successfully uploaded.
If so, using dual mode does not seem to have significant benefits compared to its disadvantages (memory space, complexity, etc.).
Do I mis-understand something?
Thanks and regards,
Koichiro Tashiro
