Home / Web Pads / Epods One General Post DOC upgrade

DOC upgrade (modified 0 times) kuyote Profile hello, I recently submitted a request to m-sys, for any information on upgrading the DOC of my Epod, I will paste the reply that they had given to me: I recommend to download the associated driver for the OS that you are trying to do. I have attached version 5.0 of the utilities and firmware. You will have to boot into DOS and run the dformat command to erase anything that is exsisting on the device. Implementation into the OS that you are porting it to is within the readme file for the driver. Boot into DOS, and go to the DOC utils. Run docpmap /i to determine the memory address the DOC is jumpered to. Run dformat /win:XXXX /s:doc50.exb **Remember to replace XXXX with the memory address. Reboot your system, and follow the steps in the readme.txt for the driver you will be using. I noticed on the m-sys webpage that they have a socket for the flush mounting millenium chips, so you can program them, it looks like it is the same pin count as there 2000 chip's which I believe are on the Webplayers. My questions is, do you think it would be possible to remove the DOC from the epod, put it in the socket for programming, and place it into the webplayer to be programmed, since it can be booted of of a hard drive.. Thanks for any help 09-20-2001 10:08:07

RE:DOC upgrade (modified 0 times) Glitch Profile kuyote: IMHO, what you are proposing is perfectly feasible. If the DOC TSOP package is shipped preformatted (it likely is) then there is no need for the TSOP/DIP adapter. You could remove the current DOC from the daughterboard and replace it with the new one. If you have applied the DOC disable hack you could use the ePods itself to transfer the files to the DOC. I only suggest doing it this way because the TSOP/DIP adapter is probably expensive. If you have more than a few of these to program it may be easier to use an adapter and a Webplayer to load the DOCs. I see a few problems with doing this upgrade. The first is finding a source for the TSOP package DOC's. I can't recall ever seeing them for sale. Then again, I've never specifically look for them. The next problem is cost of the DOC. You can do most everything with Compact Flash cards as you can with DOC at a fraction of the cost (and effort). The last problem is working with the surface mount components. If you are used to working with SMD then it is no big deal. Otherwise you could trash your ePods. These problems are fairly minor ones. Let me know if you find sources for the parts. If they are reasonably priced I may want to give your idea a try. Have you tried getting samples from M-Systems?

RE:DOC upgrade (modified 0 times) NetWorkS Profile | Email Hello, I need to replce the DOC on my ePods unit. I have already removed the DOC from the daughterboard since i thought that it was the problem when my unit was not responsive (i did not see the DOC disable hack). From what i understand, i would need the 32-pin DIP DiscOnChip 2000 package from M-Systems as the replacement. Can someone confirm this?? Also, will the 16Mb replacement be a problem, or must i absolutely use an 8Mb DOC?? Glitch: you mentioned being able to use the ePods without a DOC, is this possible? or must i absolutely have a DOC to use the ePods? Thank you in advance for any help. NetWorkS 02-19-2002 11:39:40

RE:DOC upgrade (modified 0 times) Glitch Profile NetWorkS: AFAIK, the ePods needs the DOC to work. There is a chance that it could boot from ROM and then load the rest of the files from compact flash (instead of the DOC). I have not tried this to confirm it one way or the other. What I trying to say in my previous statement is that if one wanted more storage space, that CF is a cheaper/easier than replacing the DOC with a larger one. I am still interested in trying the "bigger DOC hack". I would be willing to "guinea pig" one of my machines. Right now I don't have the time to track down the parts. If you find a source for the TSOP DOCs, please let me (and everyone else) know. Glitch Electronics run on smoke, if you let the smoke out they won't work 02-20-2002 21:48:34

RE:DOC upgrade (modified 0 times) NetWorkS Profile | Email I have managed to find a supplier that claims he can get me a 16Mb M-Systems DOC DIP package (the TSOP package is 48 pins). I have tested all traces on the daughterboard and they seems fine... I have not however etsted the Flash ROMs. I have access to an oscilloscope, but i don't know if i have a probe thin enough to make contact with only one pin at a time. I will post when i have any more info. Glitch: btw, do you have any more RAM upgrade packages left? NetWorkS 02-21-2002 10:19:05

RE:DOC upgrade (modified 0 times) Glitch Profile NetWorkS: The ePods uses a 32-pin TSOP-II package. You may be able to hack in a DIP package if you connect the pins via fine wire (wirewrap wire) to the pads on the daugherboard. Be sure to watch the pinouts since they are not one-to-one. I'm not sure if you would be able to get the cover back on with a dip package installed. The DIP packages are fairly easy to find. I would try to buy one used if you want to experiment. IMHO, new ones are too expensive. Contact me via email about the kits. Glitch Electronics run on smoke, if you let the smoke out they won't work 02-21-2002 21:42:06
