Hi everyone. I was working with an MCB2388-Eval-Board (lpc2388), and I was downgrading to my own pcb with a lpc2387. I realized problems with my board, but at this time now, I don't want to give any code. Later, if necessary.
As far as I know, all "lpc23xx"-devices use the same headers. For sure my pins and the layout are correct, I checked it several times.
** First question is: are there any known differences in the basic-setup from lpc2388 to lpc2387? like CLK-init, UART-init,.... (the uart0 is my troublemaker, ...so I dont trust my CCLK, PLL and this stuff.) I expect: no.
second question: are there any "you-have-to-set-by-first-programming"-fuses?? (if so, I really should read more about my architecture, I know) I expect: no. **
I am debugging at the moment, so my question is only about known differences. (Perhaps it has a quite simple solution.) And yes, I got the manual. And I read a lot ;-) Thank you very much, I am happy for any idea. Matthias
"I don't remember any difference." This is quite important to me. Thank you very much.
Im checking the GPIOs at the moment. They are working!! --> So CLK, PLL, 72MHz, etc. is ok. (maybe I had a short yesterday, well, I willnot find out...)
I will setup my code from the beginning, and check each single change. I really thought, its a one-day-procedure. Thank you with regards Matthias
PS: TX is not toggeling. UART is working in the old source-code, it should be powered. and yes, I should look into the registers... never done. I will keep that in mind.
Hi, just as a short reply, my software is working in its old unchanged version. What I forgot: the LCD has to be installed. The source-code hangs up (waiting for a busy-answer!) without LCD. %&"§$% ;-)
Maybe there were further hardware bugs.. but I think I just should have assembled everything at once and should have press "load". Everything would be fine then.
Thank you, for your advice! with regards. Matthias
