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.
I just started experimenting with JN5168-001-M00 Modules for my master thesis and now I have just the same problem. At first I can read the Device Info like shown and everything is fine
But when I want to program I get the warning "The loaded image does not appear to be compatible with the connected device. Continue?"
If I program anyway the Device Info can't be read out anymore.
Please... I need some help and can't get any further. I would be so happy If I could get some answers from you :smileyhappy:
Make sure you're flashing it with "jn5168" binary not "jn5169"
Hi David, how do I select tje jn5168? in the JN-AN-1218 there are only jn5169 .bin files
Thank you for your answer David. Actually this caused the warning message... Sorry I'm just getting into it :smileyhappy:
Furthermore I found out that the re-progamming issue had something to do with a pull-down resistor I used to set the device into programming mode. After connecting SPIMISO directly to GND without the resistor it just works fine. Seems like there is a small current flowing from the pin in programming Mode leading to a voltage drop over the pull-down resistor, high enough to keep the device from getting into programming mode
me too. Who can help we recover the chip? tks
