I believe what I am asking is extremely specific, but keeping hope that I might get some direction
I have used a clone ST- Link v2 programmer to download code into a NRF51822 Cortex M0 SOC from Nordic. In short, I have been following this guide here
http://icarus-sensors.github.io/general/starting-with-nRF51822.html
When I try to erase the flash of the chip using OpenOCD as said in the guide, I encounter this error
When I execute
nrf51 mass_erase The terminal says Unknown device (HWID 0x00000057)
Is this that the NRF51822 device is not recognised on the STLink is not recognized?
