Getting started

For any major work on MityARM SOMs you will need:

  • serial (RS232) connection to see the boot messages and to control the u-boot boot loader
  • 32GB (as small as 4GB should be okey) micro-SD flash card to boot virgin MityARM SOMs (no boot loader in onboard flash)
  • micro-SD to USB adapter to create bootable SD flash disk
  • micro-SD to normal-SD adapter to use with the Critical Link development board (normal-size SD flash socket)
  • ethernet connection
  • DHCP server, TFTP server, NFS-Root server to net-boot Linux on the SOM.

General procedure when starting from scratch:

  • power-up the SOM, observe TI boot loader messages on serial connection
  • prepare bootable SD flash disk
  • boot Linux from SD flash
  • from Linux, install u-boot boot loader and Linux kernel in the on-SOM onboard flash
  • try to boot from on-board flash (options are: continue with net-boot and continue with booting from SD flash)

A completely standalone system does not require an ethernet connection - boot u-boot from on-board flash, boot Linux and mount rootfs from SD flash. User login via serial connection or ssh over the network.

Create boot disk

  • use 32GB "class 10" MicroSD card (use MicroSD->SD adapter for CL evaluation boards)
  • partition using "fdisk" like this:
Device Boot      Start         End      Blocks   Id  System
sda1   *             1           9       72261    c  W95 FAT32 (LBA)
sda2                11         xxx      xxxxxx   83  Linux
  • newer fdisk, do this:
Disk /dev/mmcblk0: 31.4 GB, 31439454208 bytes, 61405184 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk label type: dos
Disk identifier: 0xdef3c07f

        Device Boot      Start         End      Blocks   Id  System
/dev/mmcblk0p1            2048       81920       39936+   c  W95 FAT32 (LBA)
/dev/mmcblk0p2           83968    61405183    30660608   83  Linux
[root@armdaq01 ~]# 
  • even newer fdisk (Ubuntu 16.10), do this:
Disk /dev/sdb: 29.3 GiB, 31439454208 bytes, 61405184 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x55b59316

Write PHY registers from uboot

Example for Micrel KSZ9021 PHY extended registers:

0x104: default value is 0x7777: bits are 0xqxyz
  q=RX_CLK delay, 0.2ns unit
  x=RX_CTL delay
  y=TX_CLK delay
  z=TX_CTL delay
0x105: default value is 0x7777, each 4 bits are for RXD3,2,1,0, 0.2ns unit

BOOTCONFIG

BOOTCONFIG settings:

  • CL eval board:
    • BOOTCONFIG[0..11] are SYSBOOT[0..11]
    • boot from SD: all open, [3] closed
    • boot from on-SoM NAND: all open, close [2], [3], [8], [9], [10], [11] (6 jumpers)
  • CAMAC board:
    • top-to-bottom: B0..4,G0..5,R0 correspond to LCD_DATA[0..11] are SYSBOOT[0..11]
    • boot from SD: all open, B3 closed
    • boot from on-SoM NAND: all open, close B2, B3, G3, G4, G5, R0 (6 jumpers)

NOTES:

  • boot from EMAC1 requires PHY connection to RGMII1, CLeval and CAMAC boards connected PHY to RGMII2.

To build the kernel for the CAMAC board: (there are no kernel modules to build or install)

git checkout triumf/camac

cp arch/arm/boot/uImage /var/lib/tftpboot/mityarm/uImage

If the above complains about missing "mkimage", do this:

  • shutdown -h now
  • power off
  • remove SD flash card
  • setup boot jumpers to boot from NAND flash:
BOOTCONFIG [0..11]
::[:][:]::::[:][:][:][:]
  • (to boot from MMC/SD flash)
BOOTCONFIG [0..11]
:::[:]::::::::
  • connect serial console
  • power on
  • on serial console: press <space> to get into the uboot shell
  • (notice how u-boot complains about loading default environememt)
  • on serial console, type these commands:
    • to boot from network (dhcp, tftp, NFS-root):
setenv bootcmd_orig \'${bootcmd}\'
setenv bootcmd 'run net_boot'
setenv rootpath
saveenv
    • to boot from SD flash (without changing bootconfig jumpers):
use "mmc_boot" instead if "net_boot"
  • you should see this:
U-Boot# setenv bootcmd_orig \'${bootcmd}\'
U-Boot# setenv bootcmd 'run net_boot'
U-Boot# setenv rootpath
U-Boot# saveenv
Saving Environment to NAND...

  • cycle power
  • again, press space to get into the uboto shell
  • (notice how the complaints about default environement are gone)
  • run net_boot
  • (on dhcp server, observe how we get an IP address and try to load the linux kernel)
  • on the dhcp server, add this to dhcpd.conf:
group {
	option routers 142.90.100.18;
	option subnet-mask 255.255.224.0;
	option domain-name "triumf.ca";

	option root-path "142.90.111.60:/data0/root/%s,v3,tcp,hard";

	host lxdaq30-eth0 { fixed-address lxdaq30; option host-name "lxdaq30.triumf.ca"; hardware ethernet D4:94:A1:83:61:50; } # mityarm

}
  • on the dhcp server, put uImage from the MityArm SD flash card into /var/lib/tftpboot/mityarm
  • on the dhcp server, "server dhcpd restart", "tail -100f /var/log/messages"
  • on the MityArm serial console, reset, press <space> to get the u-boot prompt, say "run net_boot"
  • on the dhcp server, observe we get an IP address, we tftp load "uImage", try to mount the root filesystem
  • on the MityArm serial console, observe we get an IP address, tftp load the kernel, start the kernel, try to mount the root filesystem.
  • root filesystem should be at /data0/root/lxdaq30.triumf.ca created by "rsync -av" of the SDflash root filesystem.

Create initramfs

cd .../rootfs
find . | cpio -o -H newc | gzip > ../rootfs.cpio.gz
  • in linux kernel menuconfig set initramfs to .../rootfs.cpio.gz
  • make sure there is a "/init" in the initramfs - that's what is executed first

Access U-Boot environement from Linux

  • create /etc/fw_env.config
# MTD device name       Device offset   Env. size       Flash sector size
/dev/mtd6 0 0x20000 0x40000
  • run: /ladd/data0/olchansk/MityARM/Fedora/Fedora-Minimal-armhfp-19-1-part3/usr/bin/fw_printenv
  • get fw_printenv for Fedora20: yum install uboot-tools

Note: ENV_SIZE comes from uboot include/configs/mityarm335x.h where it is defined as

/* Always 128 KiB env size */
#define CONFIG_ENV_SIZE  (128 << 10)

Network boot configuration

  • add this to dhcpd.conf:
# 
# group for network booting MityARM machines 
# 
 
group { 
        option routers 142.90.100.18; 
        option subnet-mask 255.255.224.0; 
        option domain-name "triumf.ca"; 
        option domain-name-servers 142.90.100.19, 142.90.100.68; 
        default-lease-time infinite; 
        max-lease-time infinite; 
 
        filename "mityarm/uImage-KO7"; 
        next-server ladd00; 
        option root-path "142.90.111.60:/data0/root/%s,v3,tcp,hard"; 
 
        host lxdaq30-512MB-linux { fixed-address lxdaq30; option host-name "lxdaq30.triumf.ca"; hardware ethernet 78:c5:e5:be:6b:6f; } # mityarm

}
  • note how there are 2 entries for each mityarm module: one for uboot and one for linux - they seem to use different MAC addresses (different by 1)
  • populate /var/lib/tftpboot/mityarm:
mkdir -p /var/lib/tftpboot/mityarm
cd /var/lib/tftpboot/mityarm
wget http://daqshare.triumf.ca/~olchansk/MityARM/uImage-KO7
  • populate the NFS-Root filesystem:
cd /nfsroot
wget http://daqshare.triumf.ca/~olchansk/MityARM/lxdaq30.triumf.ca-fedora20-20140811a.tgz
untar
rename to lxdaq30.triumf.ca (to match "%s" in DHCP root-path)
export to lxdaq30.triumf.ca with options (rw,async,no_root_squash)
add your ssh key to .../root/.ssh/authorized_keys
  • try to boot, look for DHCP messages (get the IP address), TFTP messages (loads uImage), NFS images (mounts the root filesystem)
  • try to ping, try to ssh
