Some research... Fluke 287/289 are using RedBoot/eCos: --- Quote ---eCos and RedBoot based products showcase Industrial and Automotive Fluke 289 and 287 True-RMS Multimeters. Fluke's "The Most Advanced Multimeters, Ever", data logging & graphing multimeters. --- End quote --- https://lists.ecoscentric.com/ecos/examples.shtml So I have been reading alot about RedBoot and found this: --- Quote ---Accessing RedBoot After all connections have been made, start the serial terminal application and apply power to the board. Press Ctrl+C several times on the serial terminal until you see the RedBoot> prompt. If the kernel begins to boot, reset the board and try again (the standard timeout before booting the kernel is one second). On most versions of RedBoot, you will see either a '+' or a message from RedBoot before it boots the kernel, but some configurations have this disabled. --- End quote --- http://wiki.emacinc.com/wiki/Loading_Images_with_RedBoot So the reason that I could not write to console is that I was trying to do it after the kernel has already booted. So I'll try sending in Ctrl+C every half a second and then power up the Fluke 287. Hopefully I'll be able to access console this way... |
