TDA4VM: Issue about SCI client

Dear Expert,

    Thank you for your reply and I was confused about how the board configuratoin was transfered between the SBL and MCU10_APP.As the following memory alloctation in SBL, the MCU10_APP may not get the exact address of the configuration data. So how does the MCU10_APP get the board configuration left benhind by the SBL?

These sections can directly be referred in the code, for example refer to Sciclient_getDefaultBoardCfgInfo in sciclient_boardcfg.c, the boardconfig rm, pm etc data is passed using global variables like gSciclient_boardCfgLow_rm etc and these variables directly point to .boardcfg_data. See the below snapshot from the same file:

Dear Expert,

    Thank you for your reply.

    I have built the sbl project in ti-processor-sdk-rtos-j721e-evm-07_03_00_07/pdk_jacinto_07_03_00_29/packages/ti/boot/sbl/binary/j721e_evm/cust/bin$ and check the map file.And I found that the boardcfg_data has been allocated to 41c4a180 other than the space at 0x41C8_0000. Accorrding to https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/08_04_00_06/exports/docs/pdk_jacinto_08_04_00_21/docs/userguide/jacinto/family_cfg/jacinto/index_modules_sciclient_jacinto.html#build-and-run, the 0x41C8_0000 should be allocated to store Board configuration.So I was confused that who put the board configuration to this place? 

Dear Expert,

     Thank you.
