Programming EEPROM from Linux
Hello,
The company I work for is engineering a system that makes use of the DisplayLink. It's non-x86, so can't boot windows. The DL-125 is on the PCB, so it can't be connected to anything else. We have a 128k EEPROM attached to it. None of the open source drivers (libdlo, udlfb, etc) have EEPROM programming in it. Also, I can't seem to find any generic firmware to load into it. So, I would like to know if the manufacturing tools are available for Linux, and if so, where to get them. |
Update...
I figured out that our extranet account allows building the firmware (as soon as we get a PID assigned).
I'm still wondering about how to program it, since none of the tools available for download will work for us (Linux-only non-x86 environment with built-in DL-125 chip). I'm looking for pointers to libdlo or other source patches that allow writing to the EEPROM via the I2C endpoint. Thanks |
The programming tools, only available with an NDA with DisplayLink, are Windows only. There is no Linux tool available to program the firmware into the EEPROM.
You will need a Windows system to program the firmware. Wim |
Hello,
How would I go about getting an NDA? My system seems to work best on firmware v119 or 119. The v105 or even the v120 firmware is giving me problems. I would love to be able to flash the screens I get in to v118 John |
coreboot flashrom
Probably flashrom http://www.coreboot.org/Flashrom would be a good starting point.
(Programming of mainboard BIOS, flashing on some network/graphics/raid cards on devices themselves) Eventually ask on the coreboot mailinglist? |
flashrom now has its own website http://www.flashrom.org/.
As of this writing the claim is that flashrom "Supports more than 380 flash chips, 260 chipsets, 450 mainboards, 50 PCI devices, 12 USB devices and various parallel/serial port-based programmers." So the infrastructure is there. |
