Hi all, I'm using the LPC55S14, and I can't program it, I get a message saying : Break at address "0xeffffffe" with no debug information available, or outside of program code.
If someone could tell me where the problem can come from.
Best regards
Hello
Hope you are well. I suggest you try programing a demo project in a new workspace.
Additionally, could you tell me how are you handling the PIO_5?
The state of port pin PIO0_5 at Reset determines the boot source of the part or if the handler is invoked.
If you have more questions do not hesitate to ask me.
Best regards,
Omar
Yes, it is suggested to pull up the pin to 3.3V to avoid the device from entering into ISP mode.
Please create a new workspace and import a demo project to verify if this issue still persists.
If you have more questions do not hesitate to ask me.
Best regards,
Omar
I think you will need special tools like Flash Magic, which implement the ISP protocol - and the medium supported by your MCU.
I did not have to use it with NXP controllers lately, but it's the same situation with other brands.
I think the NXP staff members here are more versed in such recovery / de-bricking problems ...
Why do I have to change lines of code to be able to access the interface to configure the peripherals and pins?
I mean, I create the project for the LPC55S14, and there are some lines where it says LPC55S16, and by changing them I can access the interface to configure the pins and clocks, otherwise I cannot.
Is this normal?
@frank_m @Omar_Anguiano When I tried to load the programme, I got a file named: script.jlink, which contains:
