how to compile the nrf52

[Shriram]

Hello, I got the solution for my previous errors, but now I'm facing new error, that now when I compile my code it gives error like invalid command name "nRF52"

ac2@ac2:~/openocd_new$ openocd -s /home/ac2/openocd_new/tools/scripts/ -f board_nrf52.cfg -c init -c "reset init" -c halt -c "nrf52 mass_erase" -c "program /home/ac2/test_nrf52/nRF5_SDK_12.1.0_0d23e2a/examples/peripheral/blinky/pca10031/blank/armgcc/_build/nrf51422_xxac.out verify" -c reset -c exit Open On-Chip Debugger 0.10.0-dev-00419-gbcaf775-dirty (2016-11-29-13:32) Licensed under GNU GPL v2 For bug reports, read openocd.org/.../bugs.html Info : The selected transport took over low-level target control.

Then you shouldn't replace your old question with your new one, you should add an answer/solution and make a new question for your new question.

Actually I missed some steps like I didnt install the libusb driver, libudev-dev, hidapi and libftdi, Bcz of these I got the error for compiling nrf52. but When I installed all these drivers then again hit the ./bootstrap and then ./configure.

It seems to me that your are not "compiling" but running "openocd" and that openocd is complaining about "-c nrf52 mass_erase". I don't know openocd, but I would guess it is trying to invoke a program named "nrf52". Have you checked that program is runnable from the command line? In other environments, there is a utility from Nordic called nrfjprog which does chip erasing.
