Hi,
We are working on the LS1021 processor. We had 3 devices (SRAM, NOR Flash, LPC4312) connected on the IFC bus. How to test those devices in the bootloader? For NOR Flash, we were able to validate through the memory read/write command. For SRAM, also we write something in memory and read back to validate that. But, we are stuck in the LPC4312 controller. How to validate that device in the IFC bus?

There is no such way.

Yes.

The testing has to be determined in accordance with the LPC4312 firmware.
I believe that dedicated test application for the MCU has to be implemented.
Is there a way to test IFC bus configurations for the corresponding device is fine? I need to validate my IFC Timing and other related parameters.
The request is not fully clear.
The IFC timings are determined by configured timing parameters.
Is there a way to calculate IFC timing values for other devices like the one excel sheet we had for NOR Flash?
Also is a memory read/write the only option to validate the IFC bus or do we had dedicated IFC bus test utilities?

Yes.
