Hi all,
I successfully programmed/debugged my applicationon this board during the past two weeks.
Today I lost the ability to program/debug the lpc1227.
I tried using:
- the LPC-Link thourgh the LPCXpresso IDE obtaining
02: Failed on connect
Bad ACK returned from status - wire error.
Emu(0): Connected. Was: None. DpID: EDB6. Info: HID64HS12
- the Jlink through the IAR workbench 6.5 for arm obtaining:
Unable to get CPU status after 4 retries. Retry?
- the Ulink2 through the Keil uVision IDE obtaining:
SWD Communication failure. (kinda..do not remember exactly..sorry)
The application currenty (if the mcu is not bricked) executing is about deep sleep mode woken up by 1Hz RTC. I notice a strange LED2 activity that blink very feebly.
I also tried to
- put ISP pin to low state during reset and
- try connecting through all the methods exposed above...
...but it didn't solve my problem.
Is there any way to recover the mcu?
Thanks for the (eventual) support. ^_^
Best regards,
Francesco
