搜到一篇帖子,说是因为使用了USB3.0的端口造成的。
Sam-Ba v2.12 -> Error h_handle returned zero [Win7] Wed Sep 18, 2013 11:38 am Hello My Sam-Ba show up message after startup window(where it picks up communication port and board): Image Error h_handle returned zero while executing "TCL_Open $target(connection)" invoked from within "if {$::argc >= 2}{ puts "-I- Retrieved arguments from command line:" puts "-I- argv 0 : [lindex $::argv0]" puts "-I- argv 1 : [linde..." (file "C:/Program Files(x86)/Atmel/sam-ba_2.12/sam-ba.exe/lib/tkcon.tcl" line 4924) invoked from within "source [file join $startkit::topdir lib/tkcon.tcl]" (x86)/Atmel/sam-ba_2.12/SAM-BA.exe/main.tcl" line 6) The main window not show up, however, the Sam-Ba process is still present in the task manager (0 percent activity). Not any patches don't help, it is still the same. How can I fix it?

If current of Power Supply be not enough, so will make errors during Erase and TST high steps and then USB port give USB not Recognized Error. if you disconnect the board from USB port before the required time or has mistakes in required steps, the PC give "USB device not recognized" error. I hope this help you. Regards. 没办法验证…… |
