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
- tar xzvf /ladd/data0/olchansk/MityARM/kit/2GB-SDflash-3-29-12/sdd1-FAT32.tgz
- umount /mnt/tmp
- mount /dev/sda2 /mnt/tmp
- cd /mnt/tmp
- tar xzvf /ladd/data0/olchansk/MityARM/kit/2GB-SDflash-3-29-12/sdd2-Linux.tgz
- 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
- 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
NOTES:
- boot from EMAC1 requires PHY connection to RGMII1, CLeval and CAMAC boards connected PHY to RGMII2.
