Debugging IS25LP064A on MIMXRT1050-EVK

Question asked by craigsmith on Jul 26, 2018

Hi,

I changed the QSPI IC from the IS25WP064A to the IS25LP064A part and swaped the resistor on R49 with R301 to supply it with 3.3v. The IS25LP064A part is the 3.3v version.

 

There is a driver supplied with MCUXpresso for LPC-Link2 for this IC but it doesn't seem to work (MIMXRT1020-EVK_IS25LP064.cfx).  Has anyone managed to successfully get this working?

 

Output attached, I also tried the MIMXRT1020-EVK_IS25WP064.cfx driver which got further along to the actually programming phase before it failed.

 

A J-Link debugger works with the same configuration so it doesn't seem to be an issue with the PCB.

 

Advice?  I think there could be a bug in the MIMXRT1020-EVK_IS25LP064.cfx driver..?
