Issues recognizing Macronics 25L3205D using UM232H-B-WE

[Jay Khan]

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)

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!

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:
