loadbin kernel.ubt, 80620000
loadbin uboot.ubt, 80800000
setpc 81EC0000
NOTE: The “NXP Demo Setup” shortcut ( ..\Software\Binaries\Programmed_Images)
expects JLink.exe to be located at "C:\Program
Files\SEGGER\JLinkARM_V356b\JLink.exe". If this is not the case on your system,
please modify the “NXP Demo Setup” shortcut.
NOTE: All .bin and .ubt files, except rootfs.ubt, should transfer to the LPC3180’s
SDRAM within a few minutes. The rootfs.ubt file may take up to 5 minutes to finish
downloading depending on its size.
To run u-boot for NAND flash programming, it is necessary to enter the following
commands into a J-Link Commander window. A new J-Link Commander window must
be opened if the above commands were not typed in manually.
setpc 81EC0000
g
After performing the above command, you will only have a few seconds to react and
enter U-Boot command prompt mode.
