Upgrading DSLogic Basic to Plus without EEPROM modification
<< < (4/21) > >>

Hi Microcheap and pgo

I noticed a strange thing. When I ran the modified DSView file as pgo said (Offset EE9AC2, EE9B52 change  data from 21 to 20) the analyzer is detected as BASIC and works perfect as BASIC (buffer 163us @ 400MHz). Then without disconnecting the analyzer from usb I closed the modified DSView program and turned on the original one. Then the analyzer is recognized as PLUS and works perfect as PLUS version (167ms buffer @ 400MHz). If I disconnect the analyzer from the USB and connect again (or restart original DSView.exe ), the analyzer is recognized as a PLUS but does not see the rectangular signal at the input. The analyzer has been programmed with modified firmware (offset 00000003 and 0000186A change from 21 to 20).

After reading this thread, I ordered a USB programmer with SOIC-8 clip and a (MT48LC16M16A2) memory chip to upgrade my DSLogic basic. I will try the 'fx2lafw_eeprom_loader' tool first and if I can't get it to work I can desolder the flash chip if necessary. Hopefully the memory chip and programmer will arrive next week if the E-Bay estimates are accurate.

I have a basic that isn“t upgraded yet. Where all would I have to change the memory value if I was gonna try the 512MB ram chip?

Method 2 - Re-program EEPROM in-situ
--------------------------------------------
Wire pin 7(WC) to pin 4(Gnd) on the EEPROM.  This disables the write protect. This can be done with  a fine wire e.g. wire-wrap. This is safe because pin 7 only has a pull-up to Vdd.
This allows the EEPROM to be programmed by the Cypress USB chip over the USB from a PC.
A program to do this is available at https://github.com/podonoghue/LogicAnalyser/tree/master/Software/fx2lafw_eeprom_loader
The required EEPROM images are available if you search on the web or you can simply download the image from the DSLogic and patch the PID/VID and reprogram.

I attempted to use the program but I don't have any compilers, and it won't run on Windows which it was compiled for without a pile of libraries. I'm attempting to use Eclipse and MINGW recompile it into a binary that includes all necessary libraries but it's a new experience for me. I would buy a programmer but this seems an interesting challenge.
