thanks for you quick replys!


um... this is somewhat good and bad

i slightly modified the programming circuit of the MCB900 evaluation board. i've uploaded it on a public space:
http://www.3dsmax.at.tf/lpc925_module.pdf
the microcontroller is at the left and the the programming circuit at the bottomleft.

every LPC922 i tried worked at first time. however, every LPC925 did not.

according to the datasheet, the LPC925 sould support this feature. i got the samples 2 weeks ago (i think) directly from philips. are there still some, which simply have this feature not implemente?!

since i was sure that this must work, i just exchanged the LPC922 with the LPC925 and tried to connect. first, i forgot to change the settings in flashmagic to "LPC925" but also changing this didn't change anything. i just get the error, saying that there's a timeout and that i should try at a lower baudrate. i reduced it down to 1200 - it didn't work either. watching the serial line (with "portmon"), the microcontroller doesn't reply at all.

thanks in advance!
