LPC-Link2 : Is there a VCOM when using J-Link driver ?

[ybdecawave]

Hi guys,

I am using the LPC-Link2 to debug a board under IAR ide. 

I have successfully been switching between CMSIS and J-link driver using LPCScrypt, but when using the J-link driver, I don't see any virtual com port associated to the board, only a J-link device. Is that expected ? 

In the NXP example below, it seems possible to have a virtual com port when using the LPC-Link2 as a J-link debugger (see 7:40 min)

Thanks a lot,

Hi Yves,

The firmware image for LPCXpresso V2 and V3 boards does include VCOM as of about a year ago. Make sure you are using the latest version of LPCScrypt to program your debug probe. The version for the standalone LPC-Link2 probe currently does not support this feature though.

I'll be talking to SEGGER about adding VCOM to LPC-Link2 ... the hardware does actually support it.

regards,

Brendon

Hi guys,

For the record there is apparently not VCOM interface when using LPC-Link-2 with Jlink.
