Part Number: LAUNCHXL-F28377S
Other Parts Discussed in Thread: CONTROLSUITE
Hello:
I am using CCS v7.0 running on Windows 10.
I am unable to compile the example code eqep_pos_speed from controlSUITE 3.4.4, C:\ti\controlSUITE\device_support\F2837xS\v210\F2837xS_examples_Cpu1\eqep_pos_speed\cpu01.
The error messages begin as follows:

etc. for lines 543, 546, 549, 552, 554, 561, 568, and 575.
The lines numbers are in the declaration of the structure CAN_REGS corresponding to reserved bit fields. A portion of F2837xS.h follows.
line 523 struct CAN_REGS {
line 524 union CAN_CTL_REG CAN_CTL; // CAN Control Register
line 525 union CAN_ES_REG CAN_ES; // Error and Status Register
line 526 union CAN_ERRC_REG CAN_ERRC; // Error Counter Register
line 527 union CAN_BTR_REG CAN_BTR; // Bit Timing Register

line 533 bp_32 rsvd2[14]; // Reserved
line 534 union CAN_RAM_INIT_REG CAN_RAM_INIT; // CAN RAM Initialization Register
line 535 bp_32 rsvd3[6]; // Reserved
etc.
The example code eqep_pos_speed did compile using CCS v6.4. I have uninstalled and reinstalled CCS v7 and controlSuite and deleted previous workspaces but the errors persist. Any advice will be appreciated.
Thank you in advance.
