flashrom v0.9.9-r1954 on Linux 4.13.0-16-generic (x86_64)
flashrom is free software, get the source code at https://flashrom.org
Calibrating delay loop... OK.
Found Atmel flash chip "unknown Atmel SPI chip" (0 kB, SPI) on buspirate_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 at flashrom.org if any of the above operations
work correctly for you with this flash chip. Please include the flashrom log
file for all operations you tested (see the man page for details), and mention
which mainboard or programmer you tested in the subject line.
Thanks for your help!
I am using a Bus Pirate v3 (version 3.6 on chart)
This are Bus Pirate actual dates :
Bus Pirate v3.5
Community Firmware v7.1 - goo.gl/gCzQnW [HiZ 1-WIRE UART I2C SPI 2WIRE 3WIRE KE5
DEVID:0x0447 REVID:0x3046 (24FJ64GA00 2 B8)
Trying to read a Eeprom chip cFeon EN25F16 and got this issue.
Looking for Bus Pirate I found other users to manifest prooblems with Flashrom e Bus Pirate about cFeon !
I tried to read a Macronix chip and It did good.
Then I used an CH341A programmer whit Flashrom an It reads well the EN25F16 ... so I don't know if problem
is on Bus Pirate or on Flashrom compatibility with cFeon chips.
