Best solution for programming Softdevice/Bootloader/Firmware to multiple nrf51822 from one PC.

irarykim

Hello,

I am almost finishing developement of a BLE module using nrf51822.

For mass production, I hope I can program Softdevice/Bootloader/Firmware to 10 nrf51822 using one PC. (since on my PCB array, there are 10 single boards)

Using 10 j-link is a solution, but it is a quite expensive way.

Is there any cheaper solution?

Thanks.

    This could be a solution IDAP-Link. It will be ready soon. Gang programming can be accomplished by connecting multiple IDAP-Link to a single PC via a USB hub. Each IDAP-Link then would appears to the PC as a USB drive. All that is left to do is to copy firmware file over to each drive. This could be accomplished by a batch command.

    Gang programming without PC

    The IDAP-Link feature list has been updated to include a microSD. This will allow you to gang programming without a PC. All you need is to insert a microSD card with firmware into the IDAP-Link and press the program button. It will automatically Flash program the target.

    Updated Dec 15:

    IDAP-Link can now parallel program both nRF51 and nRF52 using command line tool IDAPnRFProg.

    It sounds great! But is downloading SD/BL/FW as simple as copy and paste? How to specify starting address of BL and FW? I also need to write some values to certain Flash address. Is it possible?
