Failed on chip setup: Ep(04). Cannot halt processor.

Hi Folks,

I am working on LPC1837 based development kit, I have programmed RDK with modified USB hid code where I missed the clock configuration, from then I see the following error.

After this I am unable to flash-program or enter debug-mode,

1) Earlier to this issue, I have programmed the OTP memory bank 3, word 0 - Customer control data, Boot source selection to SPIFI, after configuring OTP region i was able to use it fine.

I tried entering the ISP mode by pulling P2_7 (user switch sw2) low and tried to program, still I see the same issue.

( I noticed D2 (yellow) & D3 (Blue) LEDs glowing), is this the right indication for ISP mode ?

Try booting into ISP mode as described in the FAQ Regaining debug access to target MCU

Dear Team,

Thanks for the response, I have tried this (Regaining debug access to target MCU) already, did not help.

Note: RDK I have, is programmed to boot from SPIF by programming the OTP region.

When I enter into ISP mode two LEDs on the RDK are glowing is this the right behavior??
Please give me some more inputs to debug this issue.

Thanks & Regards,

Vamshi G.

You have two threads running for this issue with basically identical information, so I am going to lock this one leaving the other open for future posting.
