Hi, we are developing custom bootloader for our application we are facing issue jumped application running.

So we are using External SDRAM for our project, so we configured SDRAM in boot project as well as Application project.

FAST working Scenario:

For example Our application Code Runs default nxp specified address at 0x30000000 it is working faster with expected results.

Slow scenario:

When i create the bootable image just by changing 0x30000000  to 0x30025000. application jumping successfully, but all the configured peripherals working slower, 

Try1:

We tried by keeping the boot project and application project with same configuration, but application still running slow.

 

example; if i send CAN message with 10ms from host to ECU , but ECU is taking time to to respond >15ms.

 

So how can i resolve this issue? is it any particular configuration needs to be done in boot application or while creating custom address bootable image.
