BF504F SPI slave loading.

Hello. I have a problem with SPI slave loading.

I load the program into the BF504F via the SPI slave and don't use built-in flash memory. If the processor never connects to JTAG (via ICE-1000), then the program does not work correctly after loading. After the processor is connected to the JTAG one day, then everything works fine, even after the JTAG is turned off and after the power switch is turned off/on. What could be the reason? What happens to the processor during the first JTAG connection?
