I had downloaded the code from the below link.
Issue 1 – FRDM -K82 Board.
Example code is downloading and executing as expected.
When I had placed the virtual comport example code in internal flash, I could download the code in Factory and programming mode.
After placing some of the Application codes in external flash. I could not flash the Application code in Factory mode using blhost.
a) Linker script changed, which is attached for your reference.
b) Pinmux.c changed, which is attached for your reference
c) I had followed – “Payment Solutions QuadSPI XIP Guide 1_r0.2.doc” and executed using IAR.
Issue 2 – Customer Target - uses Different NOR Flash – 1MB(Attached for your reference).
