Other Parts Discussed in Thread: TMDS64EVM,

Tool/software:

Hi Team,

I have started understanding on the TMDS64EVM, using the SDK 10.0.0.20.

From the SDK package tried to flash the UART example to ARM M4F core through built in XDS debugger, it failed to load the example and following in the logs observed.

Please suggest is anything is missing 

Logs:

CortexA53_0: File Loader: Verification failed: Values at address 0x0000000000000001 do not match Please verify target memory and memory map.
CortexA53_0: GEL: File: D:\Projects\SE_AM6442\3.Sources\2.Demo\1.uart\workspace\hello_world_am64x-evm_m4fss0-0_nortos_ti-arm-clang\Debug\hello_world_am64x-evm_m4fss0-0_nortos_ti-arm-clang.out: a data verification error occurred, file load failed.

    Hi Mallikarjuanreddy,

    From the logs it seems that you have connected to A53 core and trying to load M4F core example on it. The error is expected in this scenario.

    Please connect to M4F core and then try to load the example. It should then load properly.

    Regards,

    Tushar

    Hi Tushar,

    Yes, i found that wrong selection of the core, thanks for the hint, after selection of the Core M4F, still failed to load

    Even after many power- reboot.

    Logs:

    CS_DAP_0: Error connecting to the target: (Error -1170 @ 0x0) Unable to access the DAP. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 20.0.0.3178)

    BLAZAR_Cortex_M4F_0: Error connecting to the target: (Error -1274 @ 0x0) Error encountered during connect sequence. The specific reason is unknown but may be the result of trying to access a Core or logic that is inaccessible due to a lack of Power, Clocks, or Authentication (i.e. Security is preventing). If blocked by security, and if supported, access may be allowed after following the Authentication process. (Emulation package 20.0.0.3178)

    Hi,

    Can you please tell have you initialized the EVM properly with SBL binaries?

    Please refer EVM_FLASH_SOC_INIT

    Hi Tushar,

    Thanks, able to flash the UART (to coreM4F) example. After going through the reference EVM_FLASH_SOC_INIT. set the board into OSPI mode and flashed through the XDS.
