51422 DK cannot support program old softdevice s110 6.0.0 ?

[hawk]

I cannot program an external nRF51822 module(program old softdevice S110 6.0.0) with nRF51-DK p20 (SWD), it give message "invalid parameter error".

and i program the 51422DK without the external board by softdevice S110 6.0.0. it also give message "invalid parameter error".

51422 DK board (PC10028) can program/erase blink example for external board(51822) successfully.

what 's the problem? or 51422 DK cannot support program old softdevice s110 6.0.0 ??

Are you using nRFgo studio version 1.20.0? There was a bug introduced in this release that made it impossible to program SD prior to version 7. This was fixed in nRFgo studio v. 1.21.0.

1.21.0 fixed it.. the test result is ok.
