Hello,

 

I am working with OM13093: LPCXpresso board for LPC11C24 with CMSIS DAP probe.

 

I followed the "Release notes for the NXP LPC11Uxx Debug Probe VCOM Driver v1.0.0, 10th July 2017" to install the driver an connect the board to the computer. But the board is not recognized by my computer (Win7). It does not appear in the Device Manager, neither in "Devices and Printers", which I have already read in other threads.

 

Then I wanted to replace the firmware but also the USB ISP (shorted JP5) mode does not work.

 

No matter jumper JP5 is shorted or not, the RBG-LED (LED1) flashes alternately red, green and blue.

 

I tried it on different PCs (Win7 and Win10), also with different cables and I tried it with six different LPCXpresso board for LPC11C24 with CMSIS DAP probe. Always with the result described above.

 

Used tools/drivers:

  • MCUXpressoIDE_11.0.1_2563
  • LPC11Uxx_Debug_Probe_VCOM_v1.0.0
