Problem with SRAM on XBAR Slave Port 2

Hello team,

In one of my project I am using MPC5777C MCU there i have issue with SRAM XBAR slave port2.

I am using SRAM slave port 2 to address range from 0x40020000 to 0x4003FFFF in my bootloader software and using same SRAM slave port 2 but different address range from 0x40010000 to 0x400140d4 in my application software as a custom data section for one of my module.

But when we flash both bootloader and application we have problem with custom data section we defined in the range 0x40010000 to 0x400140d4 and control jumps from bootloader to application after flashing but halts in one application function which uses this custom data section of SRAM and eventually jumps to ISR.

However when we flash only the application software we don't have any issue with the custom data section and everything works fine.

And for your information, we are only using single core (core0) and data cache is disabled.

Any inputs for resolving this would be greatly appreciated.

Thank you!!

Regards,

Krishna duriseti.
