Is OM40005 target supported with LPCScrypt v2.0.0?

Hi. New to the NXP line and invested most of the day in attempting to reflash a simple blinky onto the OM40005 kit (LPC51U68 CPU). This new kit was sourced through Arrow in the last 24 hours. The kit is enumerating the functions mentioned in the UM11121 guide on my Windows 7 (64 bit). Confirmed through Device Manager.

The same document contains many typos. One typo is too many typos. For starters

a) J5 (section 3.2) is noted for the USB connector and should be J7.

b) P3 (FTDI) is referenced as J5 in section 4

c) USB connector is J6 (not J5 as noted in section 3.2)

d) figure 4 is wrong (J7 should be J6)

e) the cardboard printed insert has the USB connector labels reversed

etc, etc...

there are many other errors in this document as well.

This document must have been proof checked by Master Po (Kung Fu tv show), if at all.

After installing the latest LPCScrypt 2.0.0 tool -> unable to convert the first CPU onboard this kit to be either CMSIS-DAP or JLINK compatible with the scrypts.

Does this tool work?

After spending (too many) hours on this, noting the following error code from the CLI:

< see attached >

Any ideas on what we are doing wrong? We do have other kits such as Nordic NRF, many STM, Silabs tools which are working correctly and perhaps could be used to apply any required fix onto this front target CPU (LPC43).

Hi Kumar,

Sorry that you had this much trouble. For future reference, you might find the tutorials on the "Getting started" tab of the board page a useful reference.

a) J5 (section 3.2) is noted for the USB connector and should be J7.

Actually the manual is correct here. It is telling you to connect power to the board through the J5 (device) USB connector. There are other options to power the board, such as through the Arduino site (if you prefer)... the main point here is not to use J6 so the on-board debug probe isnt powered when using an external debug probe:

"To use an external Debug Probe connect the probe to the SWD connector (P1) and connect power via the micro USB connector J5"

The others were indeed typos, as is the error on the insert. I must apologize about the number of errors in this particular manual; errors can creep in any manual but there were far more here than there should have been. We are going to introduce some extra review steps to prevent a recurrence like this. The manual has been corrected now and a new version will be posted within the next week (version 1.2).

If you have other aspects of the manual that were unclear please to let us know so we can improve.

Best regards,

Brendon

Answering my own post - after many assorted trial and error attempts. Hit the jackpot.

This kit and documentation was released too early and is not ready for prime time. Hope the documentation is corrected in the next year or so.
