we are using Code Composer Studio Version: 11.1.0.00011 and the device is TMS570lc4357. While in debug mode few of the EMAC registers are not visible and it is showing error message that "unable to read". I have attached snapshot for your reference. Could you please help me in resolving the issues.
Thanks,

Hi Subash,
The debugger memory map setup is incorrect. The gel file used to set up the debugger memory map has the following lines:
/* EMIF/Ethernet Registers */
GEL_MapAdd(0xFCFFE800, 0, 0x00000100, 1, 1); /* EMIF */
GEL_MapAdd(0xFCF78000, 0, 0x00000400, 1, 1); /* CPGMAC Slave */
GEL_MapAdd(0xFCF78800, 0, 0x00000100, 1, 1); /* CPGMACSS Wrapper */
GEL_MapAdd(0xFCF78900, 0, 0x00000100, 1, 1); /* Ethernet MDIO */
As you see, the CPGMAC slave register frame is only defined to be of size 0x400. This needs to be increased to a size of 0x800. You can change this setting manually for now, I will try and get this corrected in the next update to CCS as well.
(from table 6-25 of Datasheet)
The relevant gel file is usually: C:\ti\ccsv8\ccs_base\emulation\gel\tms570lc43xx.gel if CCS is installed with the default folder-location settings.
