Ready for NAS4Free on ODROID-C1

[Daisuke Aoyama]

Hi all,

I fix problem and improve intr code.
Now iperf3 reached to over 400Mbps.
I'm doing stress test by read/write 5GB movie file via USB HDD.
Also starting widely test both rpi and oc1 on official project forum.

I miss previous mail, USB HDD is formatted by NTFS.
So, NAS4Free can use NTFS USB drive without any additional tool/step.
I retest on UFS formatted USB HDD. It seems all score is better than RPi at 900MHz.
But it still slower writing than expected.

RPi version old log is here:

Changes:
Add recent g_eli_key.c.patch.
Implement more effective CPU affinity and GIC affinity.
Reduce platform code in arm shared source. (still remain)
Improve Ether and SDHC intr code.
Fix MicroSD timeout if boot from eMMC and reboot it.

You can get latest test image of NAS4Free 9.3.0.2 for ODROID-C1(2GB eMMC or MicroSD card) from:
http://www.peach.ne.jp/archives/nas4free/test/NAS4Free-oc1-SD-9.3.0.2.1349-20150224.img.gz

Download the image, decompress it, and write it to the eMMC module or MicroSD card of 2GB or 
more capacity.
You need serial console cable or USB keyboard/HDMI display for initial IP address setup.

Current affinity/priority setting:
----------------------------------------------------------------------
GIC priority / GIC affinity / used for IRQ/ithread
0x10 CPU0 TimerF
0x10 CPU1 TimerG (reserved)
0x10 CPU2 TimerH (reserved)
0x10 CPU3 TimerI (reserved)
0x30 CPU0 Other IRQs
0x30 CPU1 SDHC, SDIO
0x30 CPU2 Ether
0x50 CPU3 USB0, USB1

Explicitly thread(taskqueue) CPU affinity
CPU2 Ether RX/TX (may not need...)
