Hardware

Found on IRC, pictures by:

• Koen provided these pictures, of the assembled and partially dissasembled phone.
• Rwhitby has posted pictures of his Neo1973 test rig
• hrw Size comparison between nokia6210, neo1973, SE k750i
• alphaone comparison of several phones running openmoko

Wishlist:

• microSD read/write speeds with various cards
  • at the moment this probably crashes Neo1973
• internal NAND read/write speeds
• raw dump from s3c2410-ts device as you touch (click)/gesture/hold down with fingers/stylus
  • raw dump when doing fake double-touch: one finger down and then tap with second finger or make gesture with second finger
  • corresponding events in X11
• some benchmarks

(Transcribed from here.)

• ATI3 & ATI9 & AT&V output from GSM modem
  • All those commands give an error, but see Hardware:AT_Commands for other results.
  • Oh, how unfortunate. TI's Calypso is not PnP (ATI9) :-) --@Dexter 15:39, 8 March 2007 (CET)
• picture of the inside of the front and back cases, with a ruler for scale, also pcb back and front with ruler, to make it easier for people considering building hardware modifications.

Software

Wishlist:

• dmesg dump
  • Currently not possible as dmesg is flooded with debug messages.--Coredump 00:38, 9 March 2007 (CET)
• pstree -Gupl output after all standard processes have started
• ps output after startup:

Connecting

By default Neo1973 has usb0 interface working. Under Linux you need to modprobe usbnet and configure usb0 interface:

ifconfig usb 192.168.0.200 netmask 255.255.255.0

Then ssh root@192.168.0.202 with empty password to get into phone.

Dialing

Dialing currently works only manually.

Audio

Wishlist:

• How is the frequency characteristics (roughly) of the two Neo1973 speakers? And how's the sound with the bundled ear plugs? You may play this 20-16000 Hz exponential sweep (MP3) to test.
