You can't add more than 32MB RAM. I've actually upgraded several psions... the greatest difficulty is always going to be finding and removing the RAM chips form somewhere else... best is a donor psion though some old RAM sticks (can't remember if EDO or SD) will do. You can use a 5mx, 5mx pro, netbook, netbook ram module, or a revo or revo plusas a donor (NOT series 5). The revo only has one ram module though, normally to upgrade a 5mx you'd want two (they are 8MB each, so you start with 2 (16MB) then add 1 or 2 to get 24 or 32MB). There are 3 distinct versions of the 5mx motherboard (there are, in fact more, but in terms of upgrading there are 3). Each 5mx motherboard has 4 spaces for RAM chips, totalling 32MB. However, some have a 2MB ATMEL (I think) flash ROM which covers two of the spaces (does not use the same pins, but prevents you from putting chips there). We never did find out how to re-write those flash ROMs. But even those with this chip in the way you can still upgrade by soldering chips on top of the existing chips and re-routing the chip select pin to a spare CS pin on the processor. I think it is pin 14. If you don't follow, I can send some pictures of my upgraded PSIONs (I've done 5mxs, 5mx pro 24s and revos). Of course, the soldering is also very trying. I've fried a few motherboards that way. AFAIK the 5mx will support any CF cards, including wifi, bluetooth and wired ethernet (yes these exist!). In the past people have had wired ethernet and bluetooth working, but I don't recall wireless. The only problem might be power constraints. Oh, also, if the card sticks out of the CF door (has an antennae or wire) you have to open the psion and tape or short the CF door open/close detect switch, as the door will be open at all times. Careful though, as EPOC will not detect cards unless this switch changes state, which can cause booting problems. You can easily completely remove the CF door too to make things neater. In terms of networking, CF is maybe not a good idea, because you have no storage space. The serial based bluetooth module is a great idea in these terms. An alternative I thought of, is to use a CF wifi card for comms, and then remove the TTL/RS232 level converter from the serial port and wire an SD card slot in its place connected to the same pins. You may even be able to use the modem control pins (DTR etc) and keep a basic serial port (RX, TX, GND), if you have enough pins (can't remember how many SPI needs - 3? Should be okay then). You'd then need to get a driver that can bit-bash an SPI port over those pins connected to the SD slot (the pins are for the serial port/UART but that is their secondary function - primary is GPIO). I believe there is an SPI port on the windermere processor (check the CLPS-7110 data sheet - they're pin out compatible), but I don't think it is connected to those serial pins. I always intended to put the SD card slot so that it could be accessed from the backup battery door (remove or relocate the backup battery) but I never got around to this. Trouble is, you need to sort the driver out. This is much easier in 2.6 - there is an SPI bus framework and a bit-bash driver which you basically just have to tell which GPIOs to use. The other big advantage of using 2.6 (well, 2.6.16+) is that you can use armel instead of arm. This gives a massive (3 to 30 times) improvement in floating point performance... so the whole system should run much faster. Also, then you can use modern distros. A newer kernel (2.6.16+) would be fantastic. There is a dual function CF out there that has wifi and 128MB storage (sandisk connect pro or plus I think its called). But its dubious whether anyone actually got both functions to work at the same time under linux. They work fine separately, but that doesnt really help matters.

Ed, do you know if it's possible to work with SDIO cards using bit-bash driver? That would be a fantastic mod. If not, what kind of speed one can get for the regular SD card with bit-bash driver? Slower than with our CF slot or faster? |

Well, to be honest I'm not really sure whether SDIO is possible. It seems that SDIO uses SPI mode (rather than the full 4 bit SD) so it might be possible, but I can't find this information conclusively. But you can still add an SPI based wifi chip (like this http://www.whiznets. com/index.php/Wireless-LAN-Modules.html) even if it is not possible to do SDIO. I'd imagine this is faster than using a serial port based bluetooth/wifi chip. I think the 5mx might be able to do 256K baud on the serial port (in Linux only), but I'm not certain (think someone mentioned this on the mailing list once). I have a hunch you'd get much faster speeds using SPI over GPIO. I wouldn't expect it to be fast as memory storage though, probably not even close to CF speeds, but I really have no idea what kind of speeds you can expect (I haven't actually done this, I just know it's possible)! SPI is 1 bit in, 1 bit out, instead of the 4 bits you get with full speed SD access, and there is also the added overhead of the bit-banging driver (not much, but something). But it is still better than nothing! Another thought; given enough CS lines (and I just checked... there are 7 GPIOs from the serial port: RTS, DTR, TXD, DSR, DCD, CTS and RXD) you could add multiple SPI devices... like 2 SD cards, or a wifi chip and an SD slot, and still have a basic RX+TX, no handshaking, serial port.

I seem to remember someone mentioning ages ago that the LCD uses SPI? If you could break this out and use one of the serial lines as a chip select line (as I understand it each SPI device needs a chip select line?) you could obtain higher speeds. I've heard that SPI can achieve speeds of several megabits per second under good conditions. So this would be a major improvement on RS232. However I would guess that bit-banging it over a GPIO line with such a slow CPU is going to be a lot slower. I've seen a few examples of people implementing this sort of thing on microcontrollers like the Aurdino, so if anyone wants to have a go that might be a good source of code examples. Obviously you'll have to adapt it to work in the linux kernel. |

Thanks Petr, I'd appreciate that. For David: the specs used to be available only with an NDA. As I understand it Psion then basically said that anyone could have it as long as they were using it for Linux development, and as long as no one made it available publicly. So you don't need to sign an NDA to get a copy from somebody on this list. TBH, I doubt we'd find anyone at Psion willing to answer the question of whether we can host it somewhere. I also doubt that they truly care whether we do or not, but that doesnt mean that we should. I'm not too fussed what happens, as long as we don't lose the information... this list is much quieter than it was 5 years ago, and much much quieter than it was before that! Ideally I'd like it to be hosted on the PsiLinux website but available only to project members or something like that. Also, the CL PS-7110 (processor in Psion 5) reference manual used to be available for download from the cirrus logic website, but I can't find it anywhere at all now, only the very short datasheet which has limited useful information in it. Does anyone have a copy of this? The 5mx 'windermere' processor is basically identical to this (but is twice as fast) so it is still relevant. Does anyone know if it would be possible to merge the source code for series 5mx and 5? I've never looked at the series 5 source, but it just occurred to me that if they are that similar we ought to be able to have common kernels. Series 5 kernel is still some way behind the 5mx... >----Original Message---- >From: pet...@ep... >Date: 06/11/2009 10:05 >To: <lin...@li...> >Subj: Re: [openpsion] Everything so far... > >On Tue, Oct 13, 2009 at 03:51:42PM +0100, edw...@ti.... uk wrote: >> >> >> >> >Does the CPU have hardware SPI support?

The thing is, these days a 16MB 5mx or a 32MB NetBook are very small for Linux --- as you say, the amount of interest has dropped off considerably. However, there are a number of other operating systems that would fit very nicely. Haiku or Minix, for example, or a truly embedded OS such as Prex. So only being allowed to use the docs for Linux development is a bit of a shame (as well as deeply irritating to our BSD cousins). Without the docs the only source of information is to read the Linux source code. So, er, please remember to comment it! - -- ┌─── ｄｇ＠ｃｏｗｌａｒｋ．ｃｏｍ ───── http://www.cowlark.com ───── │ "There is nothing in the world so dangerous --- and I mean *nothing* │ --- as a children's story that happens to be true." --- Master Li Kao, │ _The Bridge of Birds_ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iD8DBQFK9wbOf9E0noFvlzgRAn/xAJ4p6rD0cF3gw9PNZAPNpl6KeMbrFwCgxfGk xtLXNkbvuvRmaH7Q0rQ0nwY= =jW7b -----END PGP SIGNATURE----- |

Does it go all the way back to Psion EPOC32 that would have potentially useful implications for the platforms of interest here ? Or could it help with porting Linux to more recent Nokia etc hardware ? I poked around a little on the source repository, but there's so much it quickly made my head hurt... [OTOH, the N900 looks pretty interesting.] Keith |

We would need anyone with the source code and/or SDKs/DDKs to maybe make what they have available now. I'm sure I have come across people in the past with these. If anyone on this list has these, would they like to let us know so that we may request a copy privately? At least that way you would not be making it publically available... Also I got a N900 yesterday - super little device. Touchscreen with stylus and keyboard - sound familiar? Runs linux (Debian based) and ARM architecture, so all looking good. Just need a Psion emulator for it now... lol On 5 February 2010 14:40, Keith Mitchell <ps...@ke...> wrote: > Talking some time back about Psion intellectual property rights.. > > edw...@ti... wrote: > > > For David: the specs used to be available only with an NDA.

I would like copies of all of those if that's okay. I'm pretty sure the ARM reference manuals are still widely available on the interwebs. But don't worry, I wont publish any of them!
