Hello all. I'm trying to use openocd-0.2.0 for debugging the microcontroller imx31 via parport. I use the unmodified imx31.cfg and parport.cfg of openocd. I have a few questions: 1. In imx31.cfg mentions "imx31.whatchacallit". The documentation for imx31 I read that in the chain may be three TAP: cpu-tap, sdma-tap and sjc-tap. What does it mean to "imx31.whatchacallit" in this case? 2. In imx31.cfg mentioned SJC TAPID == 0x2b900f0f. Please tell where in the documentation for imx31, which contains this TAPID? 3. When I run openocd, I get an error in the log: --- nfo : JTAG tap: imx31.sjc tap/device found: 0x2b900f0f (mfg: 0x787, part: 0xb900, ver: 0x2) Info : JTAG Tap/device matched Info : JTAG tap: imx31.cpu tap/device found: 0x07b3601d (mfg: 0x00e, part: 0x7b36, ver: 0x0) Info : JTAG Tap/device matched Warn : Tap/Device does not have IDCODE Info : JTAG Tap/device matched Info : JTAG tap: imx31.smda tap/device found: 0x2190101d (mfg: 0x00e, part: 0x1901, ver: 0x2) Info : JTAG Tap/device matched Error: Could not validate JTAG scan chain, IR mismatch, scan returned 0x0C2011. tap=imx31.whatchacallit pos=9 expected 0x1 got 0 Warn : Could not validate JTAG chain, continuing anyway... Info : found ARM1136 --- What does it mean "Could not validate JTAG scan chain, IR mismatch, scan returned 0x0C2011. tap=imx31.whatchacallit pos=9 expected 0x1 got 0" ?
