Board support for at91rm9200dk

- [TOP] - -

- "at91rm9200dk" is updated to use a linux like API for gpio. - A new target "at91rm9200dk_df" is defined to support boot from dataflash. -

- -

Board support for at91rm9200ek

- [TOP] - -

- The "at91rm9200ek" BSP supports booting from a parallel flash. - The "at91rm9200df" BSP supports a generic target booting from dataflash. -

- -

Board support for at91sam9g20ek

- [TOP] - -

- The "at91sam9g20ek" target with dataflash(card) and NAND boot support. -

- -

Minicom extensions

- [TOP] - -

- "sx-at91" is a reliable X-Modem application allowing download to the at91rm9200 - based board -

-

- "raw-at91" is a download application which will download binary data using minicom. - Typically used to download an environment script. -

- -

New command: factory

- [TOP] - -

-

factory

-

- -

- "factory" will set a selected set of environment variables - back to the compile time default. The following will give some - hints on capabilities, but is not yet complete. -

- -

- It will generate a set of scripts which will facilitate downloading - the kernel and root file system using tftp and will also - add commands to store into and retrieve from flash -

- -

New command: os

- [TOP] - -

-

os

-

-

- "os" computes a new name for the linux kernel -

- -

New command: fs

- [TOP] - -

-

fs

-

-

- "fs" computes a new name for the file system -

- -

New command: setargs

- [TOP] -

-

setargs

-

-

- "setargs" will create new bootcmd/bootargs combination from - kernel name, filesystem name, and rootfs type. -

- -

New command: led

- [TOP] - -

-

led [green | yellow | red | all ] [ on | off ]

-

- -

- "led" will turn on or off the specified (coloured) led -

- -

New command: ethinit

- [TOP] - -

-

ethinit

-

- -

- "ethinit" can be used to delay the boot of linux, until a valid network - connection has been established. This is useful if the machine is NFS mounting - the root file system and both this machine and the NFS server are powering up - simultaneously. The NFS server could take a lot longer to boot, and waiting - for this to boot may be neccessary for proper operation. -

- -

- [TOP] - -

-
