I am currently using a PandaLand 32G SD card in my Pandaboard ES, with
OSupg2beta (06-Sep-2013) and I have just upgraded to ArminiXsp3
(24-Oct-2013).
This gives me RISC OS 5.19 (06-Jul-2013) and the shutdown and restart
(CTRL-SHIFT-f12) gives me a window offering the 'Are you sure you want
to shut the computer down?' window with 'Restart', 'Shutdown' and
'Cancel' as the options. Choosing 'Restart' does, indeed, cause the
Pandabaord to do a power-on restart. All is therefore well.
The files in !Boot.Loader are as follows:
MLO 13:01:08 27-Feb-2012 23 kbytes - see below
U-BOOT/BIN 15:06:48 31-Mar-2012 241 kbytes - PandaOS1= CG's pandaboot
BOOT/SCR 11:53:52 25-Mar-2012 152 bytes - reqd? but not supplied
riscos 17:22:38 06-Jul-2013 4 Mbytes - see below

MLO1500 08:08:20 06-Apr-2012 24 kbytes - ex CG's pandaboot

riscos5199 17:22:38 06-Jul-2013 4 Mbytes - OSupg2beta (inc. SR)
Info 16:34:06 06-Sep-2013 1650 bytes - to tell me all this
I thought that I shouldtry to get back to a 'standard' set-up but if I
rename or delete the file 'BOOT.SCR' (which was originally provided
and contains the commands:
'RISC OS PandaBoard boot script'
fatload mmc 0:1 0x4030C000 cmos
fatload mmc 0:1 0x81000000 riscos
go 0x81000000
which start up the Pandaboard with RISC OS) then nothing happens when
I power on. OK let's leave that as it is for the moment.
I then upgraded the firmware using Chris Gransden's pandaboot.zip
(http://www.cgransden.co.uk/downloads.html) so that I have added the
following files (the others are already up to date):
preEnv/txt 12:15:52 17-Apr-2012 29 bytes
contains the command preenvcmd=setenv bootdelay 0
uenv_cmos/txt 07:25:46 17-Apr-2012 100 bytes
contains commands uenvcmd=fatload mmc ${mmcdev} 4030C000 cmos;
fatload mmc ${mmcdev} ${loadaddr} riscos;
go ${loadaddr}
as files 'PREENV/TXT' and 'UENV/TXT'. I have also renamed the file
'BOOT.SCR' as '_BOOT.SCR' and all is working again (so that 'BOOT.SCR'
is no longer required or used and I do now have a 'standard' set-up).
I have also included the 'smartreflex' folder (from CG's pandaboot) in
!Boot.Choices.Boot.PreDesk so that I can select whether the CPU is
clocked up to 1500MHz or 1200MHz when working hard (the smartreflex
driver over-rides the CPU speed setting initialised by 'MLO'). I have
also updated !CPUTMon to version 2 which shows clock speed as well as
CPU temeperature.
The next step now is to try RISC OS 5.2x and so I tried the
03-Sep-2013 rom. This gives me RISC OS 5.21 (03-Sep-2013). When
selecting CTRL-SHIFT-f12 I now get the message 'Your computer is ready
to be switched off' offering just the one option 'Restart' which no
longer works (the computer just freezes). So I have reverted to RISC
OS 5.19 but it leaves me puzzled - why has something that worked been
removed again?
However on the plus side I have almost managed to get the sound
working to my satisfaction (I use a module which provides various
voices and I have had to reassemble this for the 96kHz sound on the
Pandaboard) and it's almost right now (I'm still tinkering with it)
and you can download it if you want to have a play
http://www.svrsig.org/software/Organ.zip - it offers a simple
synthesiser keyboard). Comments welcome.
