fail.txt -> TIMEOUT ???


I put your Firmware on the device. And modified the Resistors on the LPC812_max.

When I plug in the Device I see the mbed-"drive". so I tried putting your "HelloWorld" on it. The red LED blinks like forever. When it stops blinking the board remounts to the system and there 2 files one is the mbed.htm and the other is the fail.txt with "TIMEOUT" in it.

It's all the same for win7, winXP and Linux.

When I try to flash from LPCXpresso it gives me:

Ni: LPCXpresso RedlinkMulti Driver v6.0 (Sep 17 2013 18:03:45 - crt_emu_cm_redlink build 244) Pc: ( 0) Reading remote configuration Nc: Looked for chip XML file in /usr/local/lpcxpresso_6.0.2_151/lpcxpresso/bin/LPC812.xml

So what did I wrong? btw. it's my first MCU.

Can you try another PC and/or another USB cable?

Can you try the following steps:

  1. Remove LPC800-MAX from any application circuits
  2. Restore the HDK firmware image (suggest using the Win7 box)
  3. Try downloading Hello World again
  4. Post results


So i tried as told and with a different cable and a different PC.

Still the same Problem with copiing to the mbed-drive.
