TMS320F280039C: Ecdsa example comes from C2000Ware

Part Number: TMS320F280039C
Other Parts Discussed in Thread: C2000WARE

Tool/software:

Hello, 

1. When I run example of ecdsa in 280049 based on C2000Ware_5_00_00_00,

the length of sig_r_val  is 64 chars, and the length of sig_s_val is 64 chars too.

I am wonder about the length of signature R and signature S,  I always thought his length was 32,why the length is 64?

2.Also, the ECDSA library is from C2000Ware_5_00_00_00 has been tested and verified for use?

Another topic in E2E is related to ECDSA library too.
