AWR1843BOOST: CanFD interface is not working in SBL with Uniflash

HI Cesar,

I haven't changed anything in terms of memory. I am using default memory configurations of SBL.

Is there anything I need to change in terms of memory?

Can you brief it down?

TIA,

Ramana

Hi Cesar,

I have gone through the code.In sbl.c file line number 627 they mentioned about the MPU settings as following:

/* Configure the MPU for MSS regions, DSS regions and peripherals after calling SOC init.
* BSS regions will be configured when BSS image is downloaded.
*/
SBL_mpuConfigDefault();

Can you provide me the CANFD peripheral MPU settings.

I have tried adding with following settings to the SBL_mpuConfigDefault() function...but it didn't work.

#if ((SOC_XWR18XX_MSS_MCAN_MEM_BASE_ADDRESS & (128U - 1)) != 0)
#error SOC_XWR18XX_MSS_MCAN_BASE_ADDRESS not aligned to 128 bytes
#endif
SOC_MPUSetRegion(SOC_MPU_REGION12);
SOC_MPUSetRegionBaseAddress(SOC_XWR18XX_MSS_MCAN_MEM_BASE_ADDRESS);
SOC_MPUSetRegionTypeAndPermission(SOC_MPU_STRONGLYORDERED_SHAREABLE, SOC_MPU_PRIV_RW_USER_RO_NOEXEC);
SOC_MPUSetRegionSizeRegister(SOC_MPU_REGION_ENABLE | SOC_MPU_128_BYTES);

Please provide me the valid MPU settings for the CANFD peripheral.

TIA,
Ramana

Hi Raghu,

Ramana,

Can you check by having only the receive objects in your SBL code?

Hi Raghu,

My issue got resolved . Nothing to do with message objects.

Thanks for the help.
