Part Number: TDA4VE-Q1

Hi expert

I running combined app with SBL.

#1 question

SBL will translate the code from OCMC to BTCM like this

But why still set EntryPoint address is ORMC (0x41010000) and boot?

Why not set to BTCM address? BTCM (0x5c10000) is OK?

#2 question

Why only copy 128 Bytes to ATCM?

Thanks you very much.

Apologies for delay in response on this.

SBL doesn't translate from OCMC to BTCM, it translates local BTCM/ATCM address to SOC view BTCM/ATCM address. If mcu1_0 is copying to mcu2_0's ATCM/BTCM it needs SOC view address to copy.

Reset vectors of application is of size 64 Bytes, copying reset vectors at 0x0 is good enough to boot the application
