Hi I have 2 customers experiencing issues with Bulk erase with our<br>

What can I do to help get this situation looked at? I am working on getting board names is there any other information you need??<br>
<br>
<br>
From IBM:<br>
Found Micron/Numonyx/ST flash chip "N25Q128..3E" (16384 kB, SPI).<br>
This chip may contain one-time programmable memory. flashrom cannot read<br>
and may never be able to write it, hence it may not be able to completely<br>
clone the contents of this chip (see man page for details).<br>
Write/erase is not working yet on your programmer in its current configuration.<br>
Continuing anyway.<br>
Flash image seems to be a legacy BIOS. Disabling coreboot-related checks.<br>
Reading old flash chip contents... Transaction error!<br>
SSFS: SCIP=0, FDONE=1, FCERR=1, AEL=0<br>
SSFC: SCGO=0, ACS=0, SPOP=0, COP=1, DBC=63, SME=0, SCF=0<br>
Running OPCODE 0x03 failed at address 0x001000 (payload length was 64).<br>
FAILED.<br>
