For any major work on MityARM SOMs you will need:
<pre>
* serial (RS232) connection to see the boot messages and to control the u-boot boot loader
Hello! I just started with a MityARM-335x Development Kit and I am trying to make sense of the development environment. We hope to use the MityARM-3359 SoM in several research projects (we are a subatomic particle physics research lab in Canada) on custom-built base-boards. Personally, I have experience with embedded linux development for PowerPC CPUs in the VME and FPGA (Xilinx Virtex4) environements. Here is my questions:
* 32GB (as small as 4GB should be okey) micro-SD flash card to boot virgin MityARM SOMs (no boot loader in onboard flash)
a) the USB flash drive that came with the dev kit contains some kind of virtual machine file with instructions to use some kind of Windows software to open it. We do our development exclusively on Linux - do you provide the development kit software in a linux-usable format? (I did find the TI SDK, but I do not know if it is the same as your SDK).
* micro-SD to USB adapter to create bootable SD flash disk
b) on your wiki page, many links lead to your redmine site which requires a login, for example, at
* micro-SD to normal-SD adapter to use with the Critical Link development board (normal-size SD flash socket)
http://support.criticallink.com/redmine/projects/armc8-platforms/wiki
* ethernet connection
this link requires a password the http://support.criticallink.com/redmine/projects/am335x-devkit/files
* DHCP server, TFTP server, NFS-Root server to net-boot Linux on the SOM.
are development kit customers like myself supposed to have access to these files?
 
I will start with the TI SDK for now and hope it is enough, but your information for the above two questions would be highly appreciated. Konstantin Olchanski olchansk@triumf.ca
General procedure when starting from scratch:
</pre>
* 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.

CriticalLink MityARM

Links

Useful links

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

Device     Boot  Start      End  Sectors  Size Id Type

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.

  • 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

  • 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";

}
  • 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.

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 
        host lxdaq30-512MB-uboot { fixed-address lxdaq30; option host-name "lxdaq30.triumf.ca"; hardware ethernet 78:c5:e5:be:6b:70; } # 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
