Nrf51822 UART example

[jjww]

Hey I could make UART receive work, and I found there is no RXD register for viewing during debug mode in Keil. anyone has idea on this?

most probably the svd file got corrupted. Try to uninstall and re-install the nrf-51MDK and please let us know if that worked.

Hi I tried re-install CMSIS and MDK, it still shows so.

[Susheel Nuguru]

which version of MDK did you install? I will have to look into its SVD file

This is not a good way but you can try. try copying nrf51.xml to Keil_v5\ARM\Device\Nordic\nRF51822\SVD (if you have 51822)

or copy this nrf51.xml to Keil_v5\ARM\Device\Nordic\nRF51422\SVD (if you have 51422)

I replaced the SVD file with from the one in your link, however , the RXD register is not shown. Maybe some where else goes wrong?
