A quick info: I just figured out that SEGGER's JLink commander can work with my board. I did not know it has a Linux version before. Firstly, when the JLink commander starts, it doesn't cause my board reset unexpectedly. Then a 'rx 1' (reset and delay 1ms then halt) command can reset and halt my bard and another 'g' (go) make my board run from start. Here a suspicious point is that the simple 'r' command did not work. Only 'rx n' works. If I use 'r' command, the board seemed get reset but have problem in halting, so when I use 'go', the board cannot continuous to run. Enclosed you can check the schematics of the JTAG connector on the board Any clue? -- woody I can't go back to yesterday - because I was a different person then.
