Send OPCODE 0xC7 to flash chip ask for bulk erase, sometimes it work, sometimes it stuck no response back.<br>
Same experiment for Spansion flash works fine.<br>

Open source tool flashrom clear SRWD and BP0, BP1, BP2 and BP3 bits of Status Register prior to erase and write for sure.<br>

Flashrom for "Micron/Numonyx/ST" go 4KB subsector erase in default. Enforce OPCOED 0xD8 performing 64KB erase<br>
<br>
“bulk erase” is unstable, and SPI bus stuck in SCIP SPI Cycle in progress. If you have time, we can co-work debugging it about bulk erase bus cycle jam issue.<br>

Hi I have 2 customers experiencing issues with Bulk erase with our<br>
Micron/Numonyx/ST<br>
<br>
N25Q128..3E<br>
<br>
16384<br>
<br>
SPI<br>
<br>
OK<br>
<br>
OK<br>
<br>
OK<br>

OK<br>
<br>
2.700<br>
<br>
3.600<br>
<br>
<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>

>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>
