TDA4VH-Q1: MSMC Boardcfg Mismatch

Part Number: TDA4VH-Q1
Other Parts Discussed in Thread: SYSCONFIG, TDA4VH

Hello, 

We wanted to divide the 8MB MSMC memory as 4 MB L3 Cache and 4MB SRAM.

for this we changed the Boardcfg via the Sysconfig tool, we got following generated code.

later when we tested this by giving TISCI_MSG_QUERY_MSMC SCI command we see that the start and end address of the MSMC is showing as 0x70000000 and 0x705EFFFF, which corresponds to approx. 6MB of SRAM. Please refer below snapshot

we wanted to why this mismatch in the configuration.

Thank you.

Regards,

Kishore B

    Hi Kishore,

    We are in the process of fixing the document for TDA4VH. The mapping is:

    0x8 --> 1MB
    0x10 --> 2MB
    0x18 --> 3MB
    0x20 --> 4MB
    0x28 --> 5MB
    0x30 --> 6MB
    0x28 --> 7MB.

    For 4MB L3 cache please try with 0x20.

    Best Regards,
