LPC935 block 2 security bit 0
« on: April 26, 2006, 12:14:55 pm »
I am attempting to program the security bit 0 for sectors 0, 1, 2, and 3 of an LPC935 using FlashMagic version 2.51.  After it programs my hex file and the security bits, I query the security bits and see that block 2 bit 0 is unset while blocks 0, 1, and 3 are correct.  I have found this to be true from both the Windows GUI and from the command line.  Do you know if there is a problem with the programming of this bit or with the reading of it?

You need to upgrade the bootloader in the device. Please email me using the address in my signature below for a copy.

Andy,

Can't this be made public? Philips published the _sources_ of the bootloader (as a part of one of the appnotes), so I doubt they would object...

I've just got permission so I'll add them to the web page as soon as I can. However apparently they are available on the Philips web site now. Not sure where though.
