[MR.liu]

when i use nrfjprog.exe download my application code,Change nrfjprog.exe --eraseall --program ble_module.hex --verify --reset to nrfjprog.exe --eraseall --program ble_module.hex --verify --pinreset ，then return error code 8

nRF5x-Command-Line-Tools_9_0_0_Installer.exe ，Mine is the latest

[bjorn-spockeli]

I think your path vaiable is pointing to an older version, because the arguments you are using cannot be combined in nrfjprog v9.0.0,

[MR.liu]

I have removed all older version,then install nRF5x-Command-Line-Tools_9_0_0_Installer.exe,There is still the same mistake

[bjorn-spockeli]

Can you still use the same command, i.e. nrfjprog --eraseall --program ble_module.hex --verify --pinreset? Have you tried power-cycling the device?

[MR.liu]

yes i still use the same command,and i have re-power to device
