`QSPI`

A command of the separate bcma command line; see Commands for other chip families.

QSPI debug command.

QSPI Write <data> [ Read <len> ]
FlashRead <offset> <len> [ envVAR=<var_name> ]
FlashWrite <offset> <data>
FlashErase <offset> <len>
FlashLoaD <offset> <file>
FlashDev id=<val> SiZe=<val> SectorSiZe=<val> PageSiZe=<val>

Built-in help

Write
   Write <data> to QSPI device and show the received data if 'Read'
   is specified. This utility could send commands to QSPI device
   one by one which is useful for device driver debugging.

FlashRead
   Display <len> bytes of flash content from address <offset>.
   If "envvar" is specified, the read data will be saved in the
   given environment variable <var_name>.

FlashWrite
   Write <data> into flash address <offset>.

FlashErase
   Erase <len> bytes of flash content from address <offset>.
   Note that <len> will be adjusted to sector size aligned.

FlashLoaD
   Read data from <file> and write the data to flash address
   <offset>.

FlashDEV
   Set custom device profile for flash identification.
   id=<val> - Manufacturer ID.
   SiZe=<val> - Flash total size in bytes, <val> must greater than 0.
   SectorSiZe=<val> - Sector size in bytes, <val> must greater than 0.
   PageSiZe=<val> - Page size in bytes, <val> must greater than 0.
