Other Parts Discussed in Thread: UNIFLASH

Hi Champ,

I am asking for my customer. 

Using CCS 20.5.0 and UniFlash 9.5.0.

Adding ccs_flash_checksum calculation in flash .cmd file,

The generated checksum, we have it on CCS is

While in the Uniflash, having the setting

We get 0x822d here on Uniflash after loading the same image.

The checksum generated on CCS and Uniflash are inconsistent. 

I tried several images that CCS always get the checksum value +1 from Uniflash.

Is anything configuration wrong?

Thanks for the support.

Regards,

Johnny
