Slow "bursty" performance when running Stand Alone SW on target board

When running the SW application directly on the Target Board some part of the GUI (upper part of a twin statusbar using uC/GUI) appears immediately, then there is several seconds where nothing happen...

No if the .text section points to the SDRAM, then your software can't directly run from the flash. You will have a bootloader and the software will be copied to RAM.

Is your application writing anything to the JTAG UART? If yes try to disable all those printfs, I discovered with some drivers that printing to the Jtag Uart while there was no terminal running on the other end could stall the CPU sometimes.
