Other Parts Discussed in Thread: C2000WARE

Hi Team,

My customer find a conflict of the register offset description between the TRM and the CCS Memory browser view:

spruii0d_TMS320F2838x Real-Time Microcontrollers With Connectivity Manager TRM (Rev. D) shows that the address of McanRegs_MCAN_RXESC is 0x0005_C6BC:

(P5096 & P5110)

But in CCS Memory browser view, it is 0x0005_C6A8:

It lead operation failed to change the value of McanRegs_MCAN_RXESC by using driverlib.

Thanks & Regards,

Yale Li

Yale,

The register offset description in the TRM is accurate, and the driverlib function is based on the same offset as well. It has been validated that using the driverlib function can be accurately used to set the data field sizes, which can be verified by looking at the Message RAM in the Memory Browser itself.

The bug here is that the offset has been incorrectly stored in the CCS Register View XML, which will be fixed. Just to reiterate, the functionality is intact, just that it is not being correctly shown in CCS.

Thanks.
