LAUNCHXL-CC1310: Can I remapp the SPI0 lines in CC1310_LAUNCHXL.h?

Hi TER,

TER said:

Yes as long as you have not mapped the DIOs to something else. 

Now what do you mean by this? Do you mean as long as I did not change anything in ioc.h?

Ok Thanks TER.

Hi TER,

As you suggested I changed the SPI lines mapping to correspond to our custom board. However I see this function 'Board_initHook()'  ->  'CC1310_LAUNCHXL_shutDownExtFlash' that shuts down the flash where the SPI lines are being configured. Now these correspond to some other lines for our custom board. Also see this thread for the ongoing problem I am having regarding our custom board. https://e2e.ti.com/support/wireless-connectivity/sub-1-ghz/f/156/p/875168/3242287#3242287

Could it be that leaving the code in CC1310_LAUNCHXL_shutDownExtFlash() as is, is causing issues?

Awaiting your reply,

Thanks in advance,

Also, what do the comments beside the SPI lines mean?

#define CC1310_LAUNCHXL_SPI0_MISO             IOID_8          /* RF1.20 */
#define CC1310_LAUNCHXL_SPI0_MOSI             IOID_9          /* RF1.18 */
#define CC1310_LAUNCHXL_SPI0_CLK              IOID_10         /* RF1.16 */
#define CC1310_LAUNCHXL_SPI0_CSN              IOID_11

What happens when I remap the SPI MISO,MOSI and CLK to some other DIOs or make them 'PIN_UNASSIGNED' ?

Could you please respond as fast as possible?

Thanks in advance,

- The comments refer to which pin used on the development board. 

- To understand your problem with pin mapping, the easiest would be to look at your schematic. 

Ok Thanks TER
