usbd_hid_composite in SDK15.0.0 cannot work in debug mode

[Mihua]

Hi,

I am running nRF5_SDK_15.0.0_a53641a\examples\peripheral\usbd_hid_composite and find it can work in standalone mode. However, if I go to Keil or IAR debug session and then run it, it cannot work as expected. This observation is present in PCA10056 V1.0 and V0.12.0 revision. V0.9.2 and V0.9.0 revision don't have this issue. Can you help to check it out?

Regards,

Kevin

I can make it work here, so I guess I need a bit more information to possibly recreate it here. I did reset, stop, and start in the debug session from Keil.

Do you use V1.0 PCA10056? is your board LED3 and LED4 lit when in debug mode? Do you change the original code?

[Kenneth]

That is correct. I do however press one time on the IF BOOT/RESET button.

You are correct. To let Keil and IAR work in debug mode, IF BOOT/RESET button must be pressed. However, SES can work directly without pressing IF BOOT/RESET button.
