    Hi,

    It depends on the MPU setting which may restrict the memory access. In SBL MPU setting is bypassed which will cause this restriction.

    /* MPU is configured by SBL. Bypass the default configuration. */
    socCfg.mpuCfg = SOC_MPUCfg_BYPASS_CONFIG;

    MPU setting of HSRAM is available in SOC_mpu_config function of soc_xwr16xx_mss.c file which you need to copy to SBL_mpuConfigDefault function of SBL to access HSRAM.

    Please check and modify accordingly. 

    Regards,
