Hi,

The 100 pin version of the LPC4370 does not have a lot of user I/O, so if possible I would like to reuse the BOOT pins after startup.

On the LPCLink2 card, after bootup the BOOT0 pin is reused to control the on-board LED.

On a new  LPC4370 board design, can BOOT1 and BOOT3 be similarly repurposed after bootup?

BOOT2 is a little more complicated. Can the single jumper be replaced by a two-way jumper - one side to ground via a resistor the other to VCC via a resistor depending on the boot mode (USB0 or SPIFI) to be used?

Thanks in advance for any help,

JohnR.
