I find there is (JTAG *) on Tool interface of 7x ED table on https://www.infineon.com/cms/en/product/microcontroller/32-bit-tricore-microcontroller/32-bit-tricor... .
Is there anything special about JTAG on TC277 ED chip? Does that mean that there is no full JTAG accessing function on TC277 ED chip?
I tried to read memory space of TC277 emulation device but got timing out error through DAS miniwiggler. Except emulation device ram space, all there memory can be accessed by DAS through Miniwiggler.

First you must unlock the EMEM (see EMEM documentation). After this you must initialize the memory (e.g write 0 to all locations), because also the EMEM is ECC protected and after power on there is no valid ECC information for the EMEM available and this result in an error when you read without initialization.

Thanks very much for your reply! Can you point me EMEM documentation you mentioned? I checked TC277 user guide and Target Specification but did not find anything about unlock EMEM sequence.

Check the user manual of TC29xB, there is a EMEM chapter.
