Pi in a box and online by itself

In a stroke of great timing, the things I ordered from Amazon arrived together.

The Pi box was easy to fit (but note if you have P5 populated, one of the supports in the case needs to be shaved away as the soldering fouls it).

The CJE RTC even fits inside. Just. But without forcing anything. ;-)

What wasn’t quite so easy was shortening all of the wires connecting the CJE board to the various LEDs. Nevermind, I got to play with my soldering iron!

Oh, yeah. That other thing. The Vonets VAP11G WiFi bridge dodah. It “only” supports b/g but not that I’d notice given my data rate is a mere 2 megabit. Thankfully it supports WPA2/AES. Setting it up required installing some stuff on the PC to configure the WiFi network information and passphrase. That bit was a doddle.
Plugging the device into the Pi, it didn’t want to connect. Since I use static DHCP, I reset the IP address to 192.168.1.10 and it worked.
I don’t know if it will work next time, mind you. According to the Livebox, “AzumiLAN” was connected, so I rather suspect the Vonets takes its MAC from whatever it is plugged into. In this case, the eeePC’s ethernet port was first. But it isn’t a big deal, just more fiddling.

[question to the floor: does anybody remember the ipconfig command to use DHCP; and does RISC OS’s DHCP check only at boot-up or can an address be assigned at any time?]

Reception was, overall, pretty poor. This isn’t a fault of the VAP11G, the iPad tends to struggle too. One of these days I’ll get around to hooking up that repeater…

So, finally, here it all is in action. Downloaded some stuff off !Store. HearSay is free now. That would be awesome if I had a serial port! :-)

Last first (this bit is at least RO) wouldn’t a re-init of the module force the issue anyway?

ipconfig would be Windows – and the answer to switch between DHCP and fixed setings of various versions is to use NETSH. NETSH INT IP DUMP will give you a copy of the current, NETSH INT IP DUMP > MYCURRENT will save those as a text file and NETSH EXEC MYCURRENT will set the interfaces to the version in MYCURRENT, edit the file to change things and save it as a different version.

NETSH /? will have you reading the tree of options for hours/days (like netsh int teredo set state disabled)

ipconfig would be Windows

Gah. I always get that wrong until the command fails. Let’s try that again with IfConfig… ;-)

Oh, and already discovered the fun of NETSH /?.

Most surprising, such interest is normally confined to geeky people :)

While I’m here, any idea what SWI &76ac4 is (apart from the X version of 56ac4) ?

The standard CJE/4D RTC should fit easily in almost all cases¹ But you have the CJE/4D Power Control/RTC module which is normally fitted with a Pi in an MiniITX/ATX case.

re DHCP on an a9Home it is *DHCP eX0
The X would have to be changed and maybe more!

¹ Unfortunately the PiBow case has a small part that fouls on our RTC module, we did send them an RTC to show how they could change the design but I haven’t been able to make contact with them since and the design doesn’t seem to have changed

Yes.

RPCEmu back door for network support.

In hostfs.h:

#define ARCEM_SWI_CHUNK    0x56ac0
#define ARCEM_SWI_SHUTDOWN  (ARCEM_SWI_CHUNK + 0)
#define ARCEM_SWI_HOSTFS    (ARCEM_SWI_CHUNK + 1)
#define ARCEM_SWI_DEBUG     (ARCEM_SWI_CHUNK + 2)
//#define ARCEM_SWI_NANOSLEEP (ARCEM_SWI_CHUNK + 3)	/* Reserved */
#define ARCEM_SWI_NETWORK   (ARCEM_SWI_CHUNK + 4)

So knowing it is a SWI entry into networking…

In arm_common.c within the opSWI function:

#ifdef RPCEMU_NETWORKING
	else if (swinum == ARCEM_SWI_NETWORK) {
		if (config.network_type != NetworkType_Off) {
			network_swi(arm.reg[0], arm.reg[1], arm.reg[2], arm.reg[3],
			            arm.reg[4], arm.reg[5], &arm.reg[0], &arm.reg[1]);
		}
	}
#endif

RPCEmu back door for network support.

Ta.

Used in the AutoSense.EtherRPCEm – I was convinced it was a check for active networking, I just couldn’t find the hook. I started looking in the source, but I’d already glazed over after a couple of long days gazing at Cisco firewall/VPN configs.¹

#define ARCEM_SWI_CHUNK 0×56ac0
#define ARCEM_SWI_SHUTDOWN (ARCEM_SWI_CHUNK + 0)
#define ARCEM_SWI_HOSTFS (ARCEM_SWI_CHUNK + 1)
#define ARCEM_SWI_DEBUG (ARCEM_SWI_CHUNK + 2)
//#define ARCEM_SWI_NANOSLEEP (ARCEM_SWI_CHUNK + 3) /* Reserved */
#define ARCEM_SWI_NETWORK (ARCEM_SWI_CHUNK + 4)

The bit at +1 (HostFS) would appear to make it easy to detect the difference between RPC and RPCEm as hardware RPC would not have &56ac1

¹ Remote access systems peer address change, web servers in DMZ etc.

re DHCP on an a9Home it is *DHCP eX0
The X would have to be changed and maybe more!

That’s ROL’s version of the OS. RO5 has a different DHCP update command – can’t remember what it is without checking, but try *Help DHCP. for the list

Silver Spoon (Gin no Saji) was one of my preferred anime of last year and Season2 just started.

Narogami could be interesting. I must say that I love non-horror youkai/kami related stuff such as Mushishi, Natsume Yuujinchu or Shigofumi.

Yuuuuuup!

I was thinking that Chūnibyō Demo Koi ga Shitai! Ren would be my favourite for this season, but I’m actually starting to suspect that Noragami will walk away with that title. I’ll shut up now, any more will be Aldershot-style gushing¹. (^_^)

¹ …not that anybody who has ever actually been to Aldershot would want to gush about it. Farnham was² much nicer. Fleet³ too.

² note: my experience is 12 years out of date; circa 2002

³ Was bored one day. Walked from Ash to Fleet. Nice afternoon. Basically this: http://goo.gl/maps/5bMzh though I went from Wellington Ave in Aldershot across to Rushmoor Road; Google doesn’t have any connection there to follow…
