Hi,
31.01.2012 0:08, Pierre Free Pascal:
Anyhow, I just discovered that
the /home directory is 99% full on that GCC compile farm machine,
meaning that only remote tests will be possible ☹
It seems that lots of developers have the same issue about finding
MIPS machines for testing ….
Would you consider the NetGear WNDR3800 680Mhz, 128MB RAM with a USB Flash
drive of 32GB to be good enough for the development of the FPC toolchain ?
(in this case, I can purchase and ship such device to your place),
or would you consider that only a qemu virtual MIPS machine which can handle
more memory and more disk space to be suitable for the development ?
I just googled a bit and read that the
USB flash drives are considered as having only a limited number of writes
before that fail... (http://en.wikipedia.org/wiki/USB_flash_drive)
So I wonder how long such a system like that would last (it probably also
depends on
the USB key quality itself?) if I run the testsuite each night
on it...
Would a small USB hard drive be better? But does the device
have enough power to support such an external drive?
Would the speed be significantly lower or is the USB 2.0
speed the real limitation?
Ok. Debian installer ran amazingly smooth and apparently debian is quite
happy with openwrt's kernel. You can see some numbers etc below. I
wouldn't say it is blazingly fast, yet it is probably close to the best
one can get of consumer-grade MIPS device at the moment. There is 10G /
and 100G /home, hdd read/write speed is around 25Mb/s. I can set up ssh
for any FPC developer(s) (though I'll need some time to fix cables etc
then) Let me know. But be aware, it is big endian.
