LPCXpresso1769 rev D1 - CRP DISABLD

[marianovedovato]

Hi everyone!

I have a LPCXpresso1769 rev D1 bought a year ago. It's new one.

When I connect it to my laptop it appears like a flash memory with name "CRP DISABLD":

Of course, the IDE can't connect to the stick because it can't see it.

I'm using in Linux Debian 9 (probed in several OS, but always with the same result), the dmesg shows:

[ 1304.007003] usb 1-2: new full-speed USB device number 12 using xhci_hcd

I'm using MCUxpresso 10.2, but it's probed in other IDEs and always it can't connect it.

Is there some procedure to resolve this?

Thank you so much!

Hi Sol, thank you so much for your help!
I tried some of the several methods from the link that you suggested without luck.

In some of those, I read that I have to enter to ISP mode, well, I pretty sure that I did because I used FlashMagic and I can flash the LPC with an image (a simple .hex) that works; I mean, the program do what they have to do.

Any help will be appreciate.

Thank you so much again!
