AM6422: AM64X: SYSFW version and SDK apply

Part Number: AM6422
Other Parts Discussed in Thread: TMDS64EVM

Hi, 

I copied, latest SYSFW  (sysfw_hs_fs_signed.h, sysfw-hs-enc.bin, sysfw-hs-enc-cert.bin, sysfw-hs-fs-enc.bin, sysfw-hs-fs-enc-cert.bin)  from version 12.01.00.33.  I took these file from 12.01.00.33.

Then, I copy paste, overwrite the same one  in  09_01_00_41. 

Then, I rebuild and recompilaiton and running at TMDS64EVM.

you will find dev boot mode doesn't work at more, the original  example of

C:\ti\mcu_plus_sdk_am64x_09_01_00_41\examples\drivers\sciclient\sciclient_ccs_init\am64x-evm

not running anymore. 

question, is there any difference between the two? either the way communicate with dmsc, or driver, clock, resource manager,   power manager,

eg:    would you list all difference? 

What is the safest way to update SYSFW, we would like to keep the same code as old version. 

Thanks
