Hello TI teams!
I works with dvr-rdk on Mistral EVM with DM8148 processor and TVP5147 video decoder. I tried to download RAM code for this decoder (from file TVP5147M1_v070300) - download completed successfully. I have a correct patch release version from ROM/RAM versions registers. But when I tried to set enable Run CRC - I always have "CRC was not performed" bit.
This is my functions that performed download patch via VBUS. Please let me know what is wrong?

After call of this function I have next print::
TVP5147: patch release = v07.03.00. crc status = 0 [NOT PERFORMED]
Please help me to fix the problem with CRC test. I'll would be glad for any advice.
And second question please - what is differences between TVP5147 patches "TVP5147M1_v070300" and "TVP5147M1_v070301"?
ThanX alot for your helps :-)
