Programming external flash via IDE fails

Hello everyone,

 

We are having issues, programming the external flash on a custom PCB via the IDE. On most of our PCBA, it works, but on other, which are seemingly identical, it does not. Swapping out the CPU or the flash IC did not fix it.

 

In the past we have been using S25FL064P, while on our newer boards a S25FL256S is placed. The driver used is the LPC5460x_SPIFI_GENERIC.cfx for which both used flash ICs are listed as supported devices in the MCUXpresso IDE User Guide.

 

The flash ICs are connected via SPIFI and the memory is configured as outlined below.

 

ICStart AddressSizeWorks?
S25FL064P0x100000000x7a1200Yes
S25FL2560x100000000x1E84800No
S25FL2560x100000000x3d09000No

 

When trying to debug the program, flashing aborts with the following output in the debug messages:

To further pinpoint the problem, I ran the SPIFI driver code from the Example directory in the MCUXpresso install folder. It crashes with a hard fault (see stack below), but gives the following output.

[MCUXpresso Semihosting Telnet console for 'LPC5460x_SPIFIdriver_Generic LinkServer Debug' started on port 49341 @ 127.0.0.1]

Flash Driver test program starting

SPIFI driver : LPC5460x Generic SPIFI Sep 14 2017 07:29:17
Detected properties
- SPIFI size : 65536 KB, 64.00 MB
- SPIFI ProgramPage size : 256 bytes
- SPIFI sector size : 64 KB
- Detected device : (null)

 

The hard fault occurs during execution of the instruction  , which reads eight words from .

 

What can cause the driver to fail that way?

 

Best regards,
