I recently received my JN516x-EK004 eval kit. I have installed the BeyondStudio environment and was able to successfully read the two DR1178 devices that came with the kit. I pulled the JN-AN-1223 application note zip from the website and so I could take a look at the Zigbee Gateway User Interface project. I then decided to load the DimmableLight_JN5169_DR1175_LED_EXP_MONO.bin file onto my devices. I did this on the first one with the EEPROM set to Erase PDM. It seems to have successfully programmed but I can no longer read that device. I did the second one but set the EEPROM to Preserve EEPROM and that one seems to be fine. I can connect to it with the previously mentioned Zigbee Gateway User Interface and I can still read the device.
I can't find a way to recover my first device. I have already spent hours digging through documentation trying to figure it out. When I use the JN51xx Production Flash Programmer it comes back with error: reading chip ID - check cabling and power. I'm hoping someone can explain what I've done and how I can recover the chip.
