Hi,
We have been using the 64k version of CC1310 for several years and had no problems. When this version went out of stock, we decided to use the 128k version.
What we do for this change is:
1.- Change from CC1310F64 to CC1310F128 in the project configuration.
2.- Modify the file CC1310_LAUNCHXL_TIRTOS.cmd
Old file (64k version):
/*

HEAPSIZE = 0x1000; /* Size of heap buffer used by HeapMem */
/* Override default entry point. */
--entry_point ResetISR
/* Allow main() to take args */
--args 0x8
/* Suppress warnings and errors: */
/* - 10063: Warning about entry point not being _c_int00 */
/* - 16011, 16012: 8-byte alignment errors. Observed when linking in object */
/* files compiled using Keil (ARM compiler) */

Results for the emmiter are good. Everything works OK, just like the 64K version.
But we have some troubles with the receiver. Almost all of the times, receiver does not react to the emmiter commands. Ocasionally, if the emmiter is really near (cm) and after lots of attempts, receiver works.
Any idea about what´s happening? (No changes in the Hardware)
Thanks for your help. Regards
