TMS320C6747: HPI BOOT failed to write DSP L2 RAM

Part Number: TMS320C6747

Hi,

The customer expects to update the firmware through HPI BOOT. Now HPIC and HPIA can be written correctly. HPID writing 0x8000_0000 ~ 0x8001FFFF Shared RAM is also successful, but writing DSP L2 RAM space 0x0080_0000 ~ 0x0083_FFFF through HPI always fails. It can be seen that HPIA is updating, and the data of L2 RAM does not change, and can see the correct handshake hrdy signal.

HPIA timing 

write 0x0080_0f00 address

HPID timing

write 0xFF01_2345
