I am working on a production run of an assembly using the LPC3250. We get a high rate of failure to program when we try to clone a board from a known good board. The clone is using the SPI ports on each assembly. All the lines on this port are used except the E13 GPI_4/SPL1_BUSY. That line is left unused and floating. Could this be causing program load failures? We also have problem with the unit dumping the program. Again could this be tied to the floating E13?
Thanks for any info on this.
