Ask 2012-oct-19
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: 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). b) on your wiki page, many links lead to your redmine site which requires a login, for example, at http://support.criticallink.com/redmine/projects/armc8-platforms/wiki this link requires a password the http://support.criticallink.com/redmine/projects/am335x-devkit/files 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
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
- remember to mark partition 1 as active (boot flag, fdisk command "a")
- mkfs.msdos /dev/sda1
- mke2fs -j /dev/sda2; tune2fs -c0 -i0 /dev/sda2
- mount /dev/sda1 /mnt/tmp
- cd /mnt/tmp
- (not this one) old boot loader from CL: tar xzvf /ladd/data0/olchansk/MityARM/kit/2GB-SDflash-3-29-12/sdd1-FAT32.tgz

- linux kernel compiled by KO:

- umount /mnt/tmp
- mount /dev/sda2 /mnt/tmp

- Fedora 20 userland:
rsync -av /ladd/data0/root/lxdaq30.triumf.ca-fedora20/ .
- umount /mnt/tmp
- eject /dev/sda
- try to boot from the new flash card

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.

NAND boot configuration
- information from here: http://support.criticallink.com/redmine/projects/armc8-platforms/wiki/UBIFS_Nand_Boot
- boot MityARM CPU, login as root
- install MLO and u-boot:
cd /media/mmcblk0p1/ flash_erase /dev/mtd1 0 0 nandwrite -p /dev/mtd1 MLO flash_erase /dev/mtd2 0 0 nandwrite -p /dev/mtd2 MLO flash_erase /dev/mtd3 0 0 nandwrite -p /dev/mtd3 MLO flash_erase /dev/mtd4 0 0 nandwrite -p /dev/mtd4 MLO flash_erase /dev/mtd5 0 0 nandwrite -p /dev/mtd5 u-boot.img
- setup boot jumpers to boot from NAND flash:
BOOTCONFIG [0..11] ::[:][:]::::[:][:][:][:]
- (to boot from MMC/SD flash)
BOOTCONFIG [0..11] :::[:]::::::::
- power off
- 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:
setenv bootcmd_orig \'${bootcmd}\'
setenv bootcmd 'run net_boot'
setenv rootpath
saveenv
- 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 domain-name-servers 142.90.100.19, 142.90.100.68;
default-lease-time infinite;
max-lease-time infinite;
filename "mityarm/uImage";

host lxdaq30-eth1 { fixed-address lxdaq30; option host-name "lxdaq30.triumf.ca"; hardware ethernet D4:94:A1:83:61:51; } # 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.
