I am trying to program (upload firmware onto) my DA14580 chip using OTP via SmartSnippets, and I am getting this error:
Additional error info at address 0x81FEC (MSB first): FF FF FF FE
Memory burning failed.
I have read in the other forums the same issue, but I have addressed the possible solutions provided and I'm still getting the error (and I have the latest version of SmartSnippets).
Some more information which may help with troubleshooting: I am using the basic development kit JTAG connection. I have tried testing the firmware using Keil. The ARM CORTEX-M SW is detected, and I can run the program but then I can't detect the BLE device with my phone. I know the code works and my connections are correct because I tried this before a few months ago and it worked, but it just won't detect anymore.
I have checked the voltage at TP2, where I have soldered a wire to interface with a connector, and it measures 6.6V (not 6.8V). Could this be the issue? Should it be 6.8V exactly? If not, any ideas what it could be?
Also, is there a header pin to connect to which allows me to calibrate the crystal? I have it connected to P0.5 in my MCU, but I can't connect it to this pin on the dev. kit board because this is occupied by my Tx wire. Is there an alternative?
Thanks in advance for your help.
