# flashprog-config(8)

read and write status and configuration registers of flash chips

## NAME

flashprog-config - read and write status and configuration registers of flash chips

## SYNOPSIS

*flashprog config \[get\] \<options\> \<setting\>*\
 *flashprog config  set  \<options\> \[**--temporary**\] \<setting\> \<value\>*

Where generic \<options\> are:

**-p** \<programmername\>\[:\<parameters\>\] \[**-c** \<chipname\>\]\
 \[**-V**\[**V**\[**V**\]\]\] \[**-o** \<logfile\>\] \[**-h**\]

## DESCRIPTION

**flashprog-config** is a utility for reading and writing status and configuration register bits of flash chips. Currently, it supports only SPI NOR chips.

## OPERATIONS

You can specify one of **get** or **set**,  or no operation which defaults to reading a setting.

**get** \<setting\>

Read and print the value of the given setting. See **SETTINGS** below.

**set** \[**--temporary**\] \<setting\> \<value\>

Write the given value to the setting. See **SETTINGS** and **VALUES** below.

When the **--temporary** option is provided, flashprog will attempt to write a temporary value that is not stored to flash. This requires special support by the flash chip for a volatile write status register command. The new value will be lost upon reset of the flash chip. Hence, it is futile to use this with external programmers that toggle power to the flash chip (e.g. Dediprog).

## SETTINGS

**qe, quad-enable**

SPI NOR flash chips often support muxing some of their pins (usually /WP and /HOLD) with additional i/o lines. This enables them to transfer four bits at once when the **quad-enable** bit is set.

## VALUES

**false**, **true**

The values **false** and **true** will be converted to **0** and **1** respectively.

natural numbers: **0**, **1**, ...

When natural numbers are given, the least-significant bits of their binary representation will be written to a setting.

## OPTIONS

All operations require the **-p/--programmer** option to be used (please see [*flashprog*(8)](/flashprog/8.md) for more information on programmer support and parameters).

- **-p**, **--programmer** \<name\>\[**:**\<parameter\>\[**,**\<parameter\>\]...\]

  Specify the programmer device. This is mandatory for all operations. Please see the [*flashprog*(8)](/flashprog/8.md) manual for a list of currently supported programmers and their parameters.

- **-c**, **--chip** \<chipname\>

  Probe only for the specified flash ROM chip. This option takes the chip name as printed by **flashprog -L** without the vendor name as parameter. Please note that the chip name is case sensitive.

- **-V**, **--verbose**

  More verbose output. This option can be supplied multiple times (max. 3 times, i.e. **-VVV**) for even more debug output.

- **-o**, **--output** \<logfile\>

  Save the full debug log to **\<logfile\>**. If the file already exists, it will be overwritten. This is the recommended way to gather logs from flashprog because they will be verbose even if the on-screen messages are not verbose and don't require output redirection.

- **-h**, **--help**

  Show a help text and exit.

- **--temporary**

  Try to use a volatile write status register command. See **set** under **OPERATIONS** above.

## EXAMPLES

To read the **quad-enable** setting of the internal BIOS flash:

**flashprog config -p internal quad-enable**

or

**flashprog config get -p internal quad-enable**

To temporarily set the **quad-enable** bit of a chip connected to an FT4222H:

**flashprog config set -p ft4222\_spi --temporary quad-enable 1**

## EXIT STATUS

flashprog exits with 0 on success, 1 on most failures but with 3 if a call to mmap() fails.

## REQUIREMENTS

flashprog needs different access permissions for different programmers. See this section in the [*flashprog*(8)](/flashprog/8.md) manual for details.
