Flash a boot code to SPI flash on AM180x?

I'm using AM1802 with SPI boot mode. I would like to write initial boot code to blank SPI flash by JTAG emulator.
I was able to burn my code with using SPIWriter and XDS100v2, but it's needed to change the BOOT Pin configuration to "emulation debug" mode.

Is there any method to write the code without changing boot pin configuration? The default setting of my system is SPI1 Flash.

Best regards,
Masa
