Hi, I'm trying to establish connection with Philips Flash Utility and an Olimex 2106 mt board without success. TheBSL jumper is shorted and the frequency set at 14745kHz (14.7456MHz). Different baudrates have been tried without success. I am not sure about the DTR/RTS settings however. Also I may be using the wrong RS232 cable. Null modem or not? I'll have to check that. I intend to use the bootloader and ICCARM. Any ideas that may help? Thanks in advance! /Anders

Hi, it's not null modem cabel that should be used with this board. You can make it by yourself. Take two connectors - DB9F for PC and DB9M for the board. Connect pins 2, 3 and 5 of the two connectors in this way: 2 <-> 2 3 <-> 3 5 <-> 5 then plug'n'play ;-) Regards, Max --- In lpc2000@lpc2..., "Anders Kjellberg" <akj@...> wrote: > > Hi, > I'm trying to establish connection with Philips Flash Utility and an Olimex 2106 mt board without success.

Anders,
I am also having problems with the Philips LPC2000 flash utility
(olimex LPC2106), and was just about to post a message on this board
to see if the problem lies with my development board.
I am just trying to upload the simple blink LED hex file to flash,
and it just comes up with cannot communicate. I too have tried many
different com ports, jumper settings and different reset conditions,
to no avail. This is the first time I have tried to use this board,
so i have no idea if the thing works.
I am almost certain the problem does not lie with the Philips LPC2000
flash utility as I have scoped out the Rx signal (3.3v low, 0v high)
on the board and found it to receive data.
However, my Tx pin on the chip is always at ground and does nothing.
Does anyone know if Tx should be held at 0v???
Not sure if this will help you Anders, but just to let you know your
not alone.
cheers,
Nick

Nick, Thanks for letting me know about your LPC 2106 problems. Since I'm working from home today I do not have any other cables but I'll get back to you as soon as I have tried a different one. As I wrote earlier, I have tested different baudrates and made sure that the comport was correctly setup. I'll check that with a scope tomorrow.

Nick, It actually works now! Olimex states 9VDC/6VAC for powering the board, but when I had a look at the closer look at the schematic it became obvious that it should be 12V... Let me know if this solves your problem as well. Otherwise I could post my LPC utility settings. regards /Anders --- In lpc2000@lpc2..., "nma550n" <nma550n@...> wrote: > > Anders, > > You had any luck yet? > > Cheers, > > Nick > > --- In lpc2000@lpc2..., "kjellberg_anders" <akj@> wrote: > > > > > > Nick, > > > > Thanks for letting me know about your LPC 2106 problems.

Anders, Great to hear you got your board working! I have not tried upping the voltage as yet, will give it a try later. The only thing that stopped me thinking that the voltage would make any differenct was that the board was getting 1.8v for the core and 3.3v for the peripherals. Are you saying it requires 12v for RS232? Also, what is voltage on your Tx pin on the LPC2106 (at default)?

Nick, I get 0V on the TX pin at 9V. It is clear from the schematic that the board won't work at 9V. I was also a bit afraid of upping the voltage as the current increased a lot. The trick is to start at 12V since the regulators draw very much current when fed below nominal voltage. After the rectifying bridge there is 7805(and the schematic says 12V there!). There is also a 1N4733 5V zener-diode. Thus, att 9V there's only 4V left for the LM1117 3.3V regulator which has a minimum voltage drop of about 1.0-1.2V minimum (4.3-4.5V in). The core may get the correct voltage but the peripherals won't. Cheers /Anders --- In lpc2000@lpc2..., "nma550n" <nma550n@...> wrote: > > Anders, > > Great to hear you got your board working!

Anders, I actually have the P2106 board and not the 2106mt board. I originally did not think the problem with the boot loader was anything hardware. I'm not sure if this will sort out the problem with my board, as there is no need to have the voltage as high as 12v (as far as i can see). I will still give this a go though. You say at 9 v your Tx line is 0v. What is it at 12v? Just trying to tie things together here. At work at the moment and can't test things till I get home. Thanks for all your help.
