BSP for several Beagle products
Specifically the beagleboard, beagleboard xM, beaglebone, beaglebone black.
More info on these targets: http://www.beagleboard.org/
This commit forms a basic BSP by combining Claas's work with
. new clock and irq code and definitions for
beagle targets (beagleboard and beaglebones), mostly
reused from the Minix codebase, thus making
irqs, ticks and non-polled console mode work too
. new timer code for ns timing with high timer resolution,
24MHz on the AM335X and 13MHz on the DM37XX
. select the console uart based on target at configure time
. removing all the lpc32xx-specific macros and code and
other unused code and definitions that the beagle bsp
was based on
. re-using some standard functions instead of lpc32xx versions
. fixed some whitespace problem in preinstall.am
. fixed some compile warnings
. configure MMU: set 1MB sections directly in the TTBR,
just to show the difference between cacheable RAM and
non-cacheable device memory and invalid ranges; this lets us
turn on caches and not rely on boot loader MMU configuration.
Verified to work when MMU is initially either on or off when
RTEMS gets control.
Thanks for testing, commentary, improvements and fixes to Chris Johns,
Brandon Matthews, Matt Carberry, Romain Bornet, AZ technology and others.

-Development board is a BeagleBoard Rev Cx. Basic initialization via stage 1
-bootloader or U-Boot will be assumed. Drivers:
+BSP for beagleboard xm, beaglebone (original aka white), and beaglebone black.
- o Standard UART 3, 4, 5, 6 (Console = 5, 115200N1)
- o Clock uses TIMER 0
- o Ethernet
+original beagleboard isn't tested.
+
+wiki: http://www.rtems.org/wiki/index.php/Beagleboard
+
+1. *** CONFIGURING ************
+
+bsp-specific build options in the environment at build time:
+CONSOLE_POLLED=1 use polled i/o for console, required to run testsuite
+CONSOLE_BAUD=... override default console baud rate
+
+BSPs recognized are:
+beagleboardorig original beagleboard
+beagleboardxm beagleboard xm
+beaglebonewhite original beaglebone
+beagleboneblack beaglebone black
+
+Currently the only distinction in the BSP are between the beagleboards and
+the beaglebones, but the 4 names are specified in case hardware-specific
+distinctions are made in the future, so this can be done without changing the
+usage.
+
+
+2. *** BUILDING ************
+
+To build BSPs for the beaglebone white and beagleboard xm, starting from
+a directory in which you have this source tree in rtems-src:
+
+$ mkdir b-beagle
+$ cd b-beagle
+$ ../rtems-src/configure --target=arm-rtems4.11 --enable-rtemsbsp="beaglebonewhite beagleboardxm"
+$ make all
+
+This should give you .exes somewhere.
+
+Then you need 'mkimage' to transform a .exe file to a u-boot image
+file. first make a flat binary:
+
+$ arm-rtems4.11-objcopy $exe -O binary $exe.bin
+$ gzip -9 $exe.bin
+$ mkimage -A arm -O rtems -T kernel -a 0x80000000 -e 0x80000000 -n RTEMS -d $exe.bin.gz rtems-app.img
+
+All beagles have memory starting at 0x80000000 so the load & run syntax is the same.
+
+3. *** BOOTING ************
+
+Then, boot the beaglebone with u-boot on an SD card and load rtems-app.img
+from u-boot. Interrupt the u-boot boot to get a prompt.
+
+Set up a tftp server and a network connection for netbooting. And to
+copy rtems-app.img to the tftp dir. Otherwise copy the .img to the FAT
+partition on the SD card and make uboot load & run that.
+
+4. *** BEAGLEBONES ************
+
+(tested on both beaglebones)
+
+Beaglebone original (white) or beaglebone black netbooting:
+
+uboot# setenv ipaddr 192.168.12.20
+uboot# setenv serverip 192.168.12.10
+uboot# echo starting from TFTP
+uboot# tftp 0x80800000 rtems-app.img
+uboot# dcache off ; icache off
+uboot# bootm 0x80800000
+
+Beaglebone original (white) or beaglebone black from a FAT partition:
+
+uboot# fatload mmc :1 0x80800000 ticker.img
+uboot# dcache off ; icache off
+uboot# bootm 0x80800000
+
+4. *** BEAGLEBOARD ************
+
+(tested on xm)
+
+For the beagleboard the necessary commands are a bit different because
+of the ethernet over usb:
+
+uboot# setenv serverip 192.168.12.10
+uboot# setenv ipaddr 192.168.12.62
+uboot# setenv usbnet_devaddr e8:03:9a:24:f9:10
+uboot# setenv usbethaddr e8:03:9a:24:f9:11
+uboot# usb start
+uboot# echo starting from TFTP
+uboot# tftp 0x80800000 rtems-app.img
+uboot# dcache off ; icache off
+uboot# bootm 0x80800000
+
+4. *** SD CARD ****************
+
+There is a script here that automatically writes an SD card for any of
+the beagle targets.
+
+Let's write one for the Beaglebone Black. Assuming your source tree is
+at $HOME/development/rtems/rtems-src and your bsp is built and linked
+with examples and installed at $HOME/development/rtems/4.11.
+
+ % cd $HOME/development/rtems/rtems-src/c/src/lib/libbsp/arm/beagle/simscripts
+ % sh sdcard.sh $HOME/development/rtems/4.11 $HOME/development/rtems/b-beagle/arm-rtems4.11/c/beagleboneblack/testsuites/samples/hello/hello.exe
+
+The script should give you a whole bunch of output, ending in:
+
+ Result is in bone_hello.exe-sdcard.img.
+
+There you go. dd that to an SD card and boot!
+
+The script needs to know whether it's for a Beagleboard xM or one of the
+Beaglebones. This is to know which uboot to use. It will detect this
+from the path the executable is in (in the above example, it contains
+'beagleboneblack'), so you have to specify the full path.
+
+
+Good luck & enjoy!

+To run RTEMS from scratch (without any other bootcode) on the beagles,
+you can comfortably load the executables over JTAG using gdb. This is
+necessarily target-specific however.
+
+1. BBXM
+
+ - For access to JTAG using openocd, see simscripts/bbxm.cfg.
+ - openocd then offers access to gdb using simscripts/gdbinit.bbxm.
+ - start openocd using bbxm.cfg
+ - copy your .exe to a new dir and that gdbinit file as .gdbinit in the same dir
+ - go there and start gdb:
+ $ arm-rtems4.11-gdb hello.exe
+ - gdb will invoke the BBXM hardware initialization in the bbxm.cfg
+ and load the ELF over JTAG. type 'c' (for continue) to run it.
+ - breakpoints, C statement and single-instruction stepping work.
+
+2. beaglebone white
+
+This has been tested with openocd and works but not in as much detail as for
+the BBXM yet (i.e. loading an executable from scratch).

+To build and run the tests for this BSP, use the RTEMS tester.

+1. Qemu
+
+Linaro Qemu can emulate the beagleboard xm and so run all regression
+tests in software. Build the bbxm.bset from the RTEMS source builder and
+you will get qemu linaro that can run them. There is a beagleboardxm_qemu
+bsp in the RTEMS tester to invoke it with every test.
+
+2. bbxm hardware
+
+This requires JTAG, see README.JTAG. Use the beagleboardxm bsp in the
+RTEMS tester. It starts gdb to connect to openocd to reset the target
+and load the RTEMS executable for each test iteration.
