| 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? |

--- Quote from: pgo on August 05, 2019, 03:30:20 am --- 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. --- End quote --- 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. |
