AFE4403-HREVM: AFE4403 Watch EVM - Problem with programming Flash memory provided with this kit.

Other Parts Discussed in Thread: MSP430F5529

Good morning;

I'm working on firmware with the board and the schematic shared with me (Thanks to SVtronics).

I have a problem with communication peripherals configuration because the SPI_MEM_CLK of flash memories is out of SPI peripheric comunication (UCA1).

And I see that de UCA1CLK it's the same pin that UCB1STE.

On the scheme we have:

Is it a mistake? Do you use the flash memories in their firmware? If It's used, how?.

Links.

Thanks!

    Juan,

    This is not a mistake. The default watch firmware does not use flash memories, but if you wanted to use it then you would have to use the port mapping functionality. That is what PM means in the pin definition. You would map UCA1CLK to P4.6.

    For more information on how to use port mapping you can look at page 26 of the MSP430f5529 datasheet, this section of the datasheet also provides a link to the User's guide.
