Is there a definitve test for s.o. who never programmed an 8051/FX2? I'm asking since I got a "LCSOFT"-board from eBay since two days and I just can't get sigrok running. I'm on Gentoo here and using the ebuilds from https://bugs.gentoo.org/show_bug.cgi?id=426586 which means using current git master. - sigrok-gtk didn't compile at all (some deprecated and now missing symbol fom libsigrok) - the fx2lafw didn't compile with the latest sdcc I can get here (which is 2.9.0). so I used the pre-compiled binaries - sigrok-qt can do a device scan fine one time and will crash on the second time ( http://dpaste.com/829833/ ) - sigrok-cli says it can only use one device at a time even when using "--device 1". found a reference here: http://thread.gmane.org/gmane.comp.debugging.sigrok.devel/323/focus=327 and worked around by disabling the "asix sigma 2" and the "demo" driver - Now sigrok-cli finds the device but will get stuck on the second time. powering off or disconnecting the device helps. console output w/o doing anything with the hardware in the meantime (between the two calls): http://dpaste.com/829836/ with strace: http://pastebin.com/54aru9gR Do I have a counterfeits or is there an easy way to check it? Or am I hitting another bug here?
