A few questions about reflashing the IP01 with Switchfin

Hello

I'm still learning about what the software options are with this hardware, and have a few questions:

1. Does the Switchfin image include a newer uClinux OS, or do I have to install this separately?

2. Besides using more recent versions of applications, what advantage is there in reflashing the Atcom IP01 with Switchfin? FWIW, here is the software that came with it, installed through BAPS:

> dmesg | more

3. I'm concerned about wearing off the NAND flash memory with too many writes. I read that the difference with the stock Atcom software (installed through BAPS) and an Astfin/Switchfin image, is that the latter software runs in RAM: Is this true? Can I run a cron script to regularly write important data to NAND flash?

/dev/root on / type yaffs (rw)
proc on /proc type proc (rw)
ramfs on /var/tmp type ramfs (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw)
usbfs on /proc/bus/usb type usbfs (rw)
securityfs on /sys/kernel/security type securityfs (rw)

4. The IP01 has no USB port, although dmesg says...
"Initializing USB Mass Storage driver...
usbcore: registered new interface driver usb-storage
USB Mass Storage support registered."

Are there Atcom appliances that offer a USB port?

Thank you.

Re: A few questions about reflashing the IP01 with Switchfin

Hi Gilles
>1. Does the Switchfin image include a newer uClinux OS, or do I have to install this separately?
Switchfin is based on the latest uClinux release 2009R1.1-RC4. You don't need to install neither uClinux nor the toolchain.

>2. Besides using more recent versions of applications, what advantage is there in reflashing the Atcom IP01 with Switchfin? FWIW, here is the software that came with it, installed through BAPS:
In Switchfin we have put
Linux kernel 2.6.26
Asterisk 1.4.32
Dahdi 2.2.1
We are working on a new nice looking GUI.

Cheers
Dimitar

Re: A few questions about reflashing the IP01 with Switchfin

Thanks for the tip. I'm reading http://docs.blackfin.uclinux.org/doku.php so that hopefully I'll be able to compile (and possibly, package) software for that appliance.

Re: A few questions about reflashing the IP01 with Switchfin

What about question 3?

3. I'm concerned about wearing off the NAND flash memory with too many writes. I read that the difference with the stock Atcom software (installed through BAPS) and an Astfin/Switchfin image, is that the latter software runs in RAM: Is this true? Can I run a cron script to regularly write important data to NAND flash?
Also... apparently, the Blackfin uClinux distro includes Lua, but it appears that Switchfin doesn't:

Code:


# ls /usr/src/switchfin/package/



asterisk

asterisk-gui

asterisk-h323

bonjour

cgic

curl

dahdi

dhcpd

lec

libpri

libtiff

libxml

lighttpd

mISDN

mISDNuser

n2n

perl

persistent

restore

rsync

sources

spandsp

sqlite3

ssmtp

tftpd

toolchain

uBoot

uClinux-dist

vim

Since Lua is very compact and this is an important point on such small hardware, how much work would it be to compile and include Lua + popular modules (LuaSocket, LuaSQL+SQLite, etc.)?

Thank you.

Hi Gilles,

Switchfin started as branch of Astfin so it follows the same general Astfin methodology.
It puts rootfs in the RAM. Portion of the NAND flash is keeping the uImage so we can boot from. Another portion is mounted as /persistant/ and is used for keep the cinfigurations, logs and CDR.
In general don't warry about too many writes in the flash using Switchfin.   

We try to keep Switchfin image small. Please describe why Lua will be usefull for thelefony applicatios and we will consider adding it.

Best Regards
Dimitar

Re: A few questions about reflashing the IP01 with Switchfin

Because it's smaller than PHP (which isn't included in Switchfin) and I find it easier to read than Perl ;-)

I need a good, rich scripting language so I can write scripts that will be called through the dialplan (extensions.conf) and handle calls.

Re: A few questions about reflashing the IP01 with Switchfin

Hi guys !

I am trying to boot an uImage via tftp the kernel booting stopped when trying to lunch init and seems that /dev/console is missing.
Which is the correct root device path  to pass to the kernel to mount  the root filesystem inside uImage (ramfs on X86)  ?

I am using an IP02 Atcom.

Many thanks for your help
Alberto

Re: A few questions about reflashing the IP01 with Switchfin

To avoid confusion on flashing using serial and uBoot i have created and exsert of Atcoms upgrade guide explaining see link below.

http://ii-tec.com/switchfin/docs/IP0X-u … -guide.pdf

Oh quick note don’t try to copy and paste the cmds (you will just end up in trouble)
