LPC2106 flash utility problem

Started by Michal Krestan February 27, 2006
I need to help with programming LPC2106 via LPC2000 flash utility. I've got
board with one LPC2106 connected via UART0 to COM1. P0.14 is pulled low, power
supply pins are in limits but I can't sucesfully connect with flash utility.
Always I get message "Cannot communicate with test board". X1 and X2
pins are connected to 7.3728MHz resonator. If I measure data between PC and
LPC2106 it has some response on flash utility requests, but no success:-( I had
several pcs of this hardware working, but this one doesn't work. I've changed
LPC2106 with new one but still with the same result.  Does anybody have idea how
to fix this problem?

Well, you don't have to use any software to connect to the LPC2106.  All 
you really need is a terminal program, something like minicom or 
hypercom will work.  Just set them to 8 bits no parity and no 
handshake.  Then start pressing the "?" key, eventually, the processor

will see the "?" and send you "Synchronized".  When it does
that, you 
respond with the same thing: "Synchronized".  You are now linked.

  I've tested this you described bellow. I'll get always response
"Sychronized", when I'm sending "?" character, but after
this, if I'll type my response "Synchronized", I'll get back for each
character typed some unknown response in form of several random characters.

Use a faster crystal?

The minimum frequency specced for serial ISP programming is 10MHz (Pg 26 of 
the LPC2106 data sheet).

Maybe isnt the frequency of your crystal?
The datasheet says the LPC2106 must have a crystal from 10 to 25MHz, and maybe 
the Flash program expects at minimum a 10MHz crystal to program the UART0 of 
the LPC.
I suggest to you to change the crystal to see if it works.

  I've tried to use 11.0592MHz crystal, but with same result:-(

	Well, it had to be checked.  Have you tried connecting with a 
terminal?  Scoped the lines?  Marginal transceivers and bad connections 
have been reported as causing problems.

Actually the datasheet says the minimum frequency is 1MHz, but 10MHz is 
needed for serial ISP. Some sort of limitation on their autobaud routines 
maybe?

Sorry if this messages dont help, but I am really happy, because the
first 
board I made (entirelly), solded (by hand, with iron solder) worked just 
fine, the ISP worked fine from the first time. Everybody here (in Brasil) is 
playing the carnival and I here working, but I am happy too. I used a 10MHz 
crystal, and had no problemas with ISP. I used a simple MAX232 powered with 
5V and I had no problems.

Are you using a purchased development board or one that you made yourself? 
If it's a purchased board, which one is it and who made it?

Thanks,
Mike

First I buyed a development board from a brazilian vendor called Elaxys 
(www.elaxys.com.br), I am using the EX_LPC_M01 wich is just nice, and cheap 
(for brazilian prices, our import taxes are simply abusive and a board 
assembled here become much more cheaper). With that board I made a few 
firmwares, and the board comes with a CDROM that contains tha gnuarm ready to 
use in Linux and Windows (of course, I use Linux), a lot of libraries made by 
Elaxys wich is MIT licensed (as seen on 
http://www.elaxys.com.br/produtos/lpc/ex-lpc-lib1/ but unfortunatelly only in 
portuguese) wich have nice functions, like one to made an routine a ISR (I 
cound not find how to do it in gnuarm alone, I can only made an ISR with 
these libraries), I buyed an Wiggler JTAG and comes in the CD too a program 
to connect GDB to the paralell port (the program is called exmon and can be 
downloaded from the Elaxys site). 
With that baord I tested the ISP program from Philips, and lpc2isp. Then I 
designed my own board, uploaded some firmwares and I am testing right now.
It is now really nice to develop im my board, because I made an ISP header 
that have an ON-OFF switch to power the entirelly board, and another switch 
that puts P0.14 low. And a DB9 caonnector to connect to the computer serial 
port. So, When I power the board with the ISP switch on, I load the firmware. 
Then I power off, turn the ISP switch off, turn the board on and the firmware 
runs, very nice. 
I developed a lot with PIC microcontrollers, using Microchip ICSP but I 
allways had to plug and unplug the ISCP connector, the ISP is just great.
Ah! another neat feature, I use UART1 in my system, and I use UART0 as a 
debug-out (I send bytes like opcodes to show me what the firmware is doing) 
so I use the same serial connection to read these caracters in minicom. 
Really nice...
