Hello everyone,
I have just discovered flashrom, and was intrigued to find that it's
possible to write PLCC chips by using an old PCI ethernet card. I have thus
acquired for real cheap an SMC1211 card which is correctly identified by my
Debian install:
00:0b.0 0200: 1113:1211 (rev 10)
I have an old BIOS chip, a PMC Pm49FL004T-33JCE that I would like to work
on, but flashrom does not seem to recognise the chip, and a verbose dump
did not help either, here is the dump:
---
# flashrom -p nicrealtek:pci=0:b.0 -VV
flashrom v0.9.5.2-r1546 on Linux 3.2.0-4-686-pae (i686)
flashrom was built with libpci 3.1.9, GCC 4.7.1, little endian
Command line (5 args): flashrom -p nicrealtek:pci=0:b.0 -VV -o probe2.log
Calibrating delay loop... OS timer resolution is 1 usecs, 1865M loops per
second, 10 myus = 10 us, 100 myus = 101 us, 1000 myus = 1035 us, 10000 myus
= 10063 us, 4 myus = 4 us, OK.
Initializing nicrealtek programmer
Found "SMC2 1211TX" (1113:1211, BDF 00:0b.0).
Requested BAR is I/O
The following protocols are supported: Parallel.

No EEPROM/flash device found.
Note: flashrom can never write if the flash chip isn't found automatically.

Now, the Pm49FL004 is a 512k chip, and I see that flashrom probes for many
different types of 512k chips, so this means that the nicrealtek program
should be able to address the 512k chips. So why does the PMC list of chips
probed does not include the Pm49FL004, but only shows these chips:

I check the flashchips.c file and thus I presume the issue lies in the fact
that Pm49FL004 only supports LPC and FWH and not the BUS_PARALLEL access,
so I am out of luck with the nicrealtek.c strategy.
Can anything be done at the nicrealtek.c level to support LPC, or is it a
hardware limitation of the ethernet NIC?
What other hardware could I use in order to read and write the Pm49FL004
chip, other than a stand-alone programmer?
Thanks for any support given!
Best regards,
Luca Bertagnolio
