New subject: Issues recognizing Macronics 25L3205D using UM232H-B-WE

3 Feb 2014


      Thanks Idwer for your quick response.
I changed the HOLD and WP to VCC still no luck; I am attaching the output with -V option; but it now does seem to detect the ID1 and ID2:
Probing for Macronix MX25L3205D/MX25L3208D, 4096 kB: probe_spi_rdid_generic: id1 0x7f7f, id2 0x7f
Still gives the error as before:
Found Generic flash chip "unknown SPI chip (RDID)" (0 kB, SPI) on ft2232_spi.
Probing for Generic unknown SPI chip (REMS), 0 kB: probe_spi_rems: id1 0x7f, id2 0x7f
Found Generic flash chip "unknown SPI chip (RDID)" (0 kB, SPI).

This flash part has status NOT WORKING for operations: PROBE READ ERASE WRITE
The test status of this chip may have been updated in the latest development
version of flashrom. If you are running the latest development version,
please email a report to flashrom@flashrom.org if any of the above operations
work correctly for you with this flash part. Please include the flashrom
output with the additional -V option for all operations you tested (-V, -Vr,
-VE, -Vw), and mention which mainboard or programmer you tested.
Please mention your board in the subject line. Thanks for your help!

Hello,
I am trying to get the Macronics Flash MX25L3205D using FTDI UM232H-B-WE
with Flashrom 0.9.7-r1764 on lunux.
The programmer UM232H seems to be supported based on
http://flashrom.org/Supported_programmers
The flash MX25L3205D seems to be supported based on:
http://flashrom.org/Supported_hardware  (MX datasheet:
http://www.macronix.com/Lists/DataSheet/Attachments/1534/MX25L6405D,%203V,%2...)
I have the following pins connected using the following mapping and
connected the MX flash using test clip:
UM232H Mapping        Macronics (25L3205D)
D0->SPI_SK                    6
D1->SPI_DO                   2
D2->SPI_DI                     5
D3->SPI_CS                    1
D4->SPI_WP                  3
D5->SPI_HOLD              7
GND        4
VCC        8    (3.13v)
That mapping looks good, and when you apply VCC power to HOLD and WP
this flash chip should be detected.
Although this wiki page is about the buspirate, the connection section
applies to a great amount of flash chips:

When I use flashrom with command line: flashrom -p ft2232_spi:type232H,
flashrom replies with "Found Generic flash chip "unknown SPI chip (RDID)" (0
kB, SPI) on ft2232_spi. Unsupported etc......
It is my understanding that the 25L3205D is supported and I am not sure why
I would get this message. Any pointers would be very helpful.
Thanks!
