Hello, 

Could you please try to install the drivers for the CMSIS-DAP debugger and virtual COM from the LPCScrypt utility?

it is a pity, after intalling the LPCScrypt Windows Installer v2.0.0(REV 2.0.0), the IAR workbench can not download the hex file..

as you know, i use the QN908x dk, is that the LPCScrypt Windows Installer v2.0.0(REV 2.0.0) suitable for qn908xdk?

Hello, 

Yes, please remember that the board has an LPC that takes care of the USB-to-serial kind of translation, so the missing driver might be the LPC instead of the QN9080 one.

thank for your suggestion!
