Hi All, This is a question for anyone with BF53x experience. I'm using a BF533 ez-kit to test my code. I'd like to make a binary file that contains code that will execute in place in flash, copy code that will run in SDRAM and then jump to SDRAM and continue running code from SDRAM. The binary file will not use the on-chip boot loader. I'm having problems including the code which runs in...

sdram - write operation takes different cycles for execution for each emu-build

I have a small piece of code which writes data into sdram memory in a loop. I always reinitialize the CYCLES as zero before this operation and then right after the write loop, I store the CYCLES value into memory. If the data buffer which I am accessing is in L1 memory, it gives the same CYCLE value for every re-build and re-run, but its never consistent for SDRAM. Working on EZ-KIT....
