CC1352P7: Wi-SUN Coap node OAD offchip flash size

Hello,

Currently the sub-1 experts are out of office. Once they return, they will respond to your question. 

Thanks,

Hi Eduardo,

The reason that the OAD project shows only 336k available is that we are showing the available flash in a given MCUBOOT slot (which is 352kb on the CC1352P7 (mcuboot data + actual application).

Hi Arthur,

But this means that we only have that size available to build the application? Or the rest of the flash can still be used?

Eduardo.

Hi Eduardo,

You can use the rest of the flash, but in that case, you will not be able to achieve onchip OAD, you will have to use the external SPI flash.

Hi Arthur,

But this is already the offchip project. Does it have the same flash configuration as the onchip project?

Regards,
Eduardo.

No, since it's already an offchip project, you can edit the .cmd linker file to edit the flash_size. 

But you also have to edit the MCU boot slot size, and most likely other things as well:

Hi Arthur,

How can I get the correct MCU boot slot size to correctly configure this? What configurations I need to set to be able to use all available flash in the MCU?

And why does the offchip project doesn't already uses the maximum flash available?

Regards,
Eduardo.

Hi Arthur,

Any suggestions on how to follow with this topic?

Eduardo.

Hi Eduardo,

We are still on the topic, we do believe that in the offchip case, we should be able to use the whole flash.

Arthur
