Hi,
I newly started working on this board.
I am trying to flash a hex file onto my lpc2138 board. But even though I flash
different hex files, I get the same output on the board. i.e. I see that the 2
LEDs glow on and off alternately.
I am now confused whether my board has a problem or I am flashing incorrectly. I
also suspect the Erase of the blocks is not happening properly. I am using Flash
Magic for flashing.
It would be great of anyone could share light on this. Also if anyone who owns
this board could flash the hex file I have got and we can compare the outputs
seen in the boards, so I can conclude whether there is a problem with my board
or something else.
Thanks & Regards,
Priyank
LPC2138 Flashing Help needed

Hi Priyank,
Typically it is quite straightforward to flash using FlashMagic. Are you
sure you haven't write-protected any memory block? Or the entire Flash of
the LPC2138?
Try checking the appropriate checkbox for "Erase all Flash+Code Rd Prot",
and in the Options, enable "Verify after programming".
Lastly (and here I have run into the same problem as you several times!),
make sure that the entire path to your hex file is correct. You could click
on the File->Information file menu and see that the file you are trying to
burn is indeed the one you have selected.
What is the message FlashMagic displays after flashing? A success message,
or a failure message?
Good luck!
Ahmad

Hi Ahmad,
Thanks for the reply.
Before I had not enabled the Verify after programming checkbox, due to which
it just showed a finished flashing message.
When I enabled the Verify after programming checkbox, the error message that
displayed was
"Error verifying. There is a difference in the Hex file value and the stored
value at address 0x00000139"
How do I check whether the memory block is write protected or not ?
I also tried checking "Erase all Flash+Code Rd Prot" and "Erase block used
by the hex file" individually but nothing changed. I guess the problem is
that the erasing is not happening.
I am sure of the hex file I am using since the flash magic also shows the
time stamp the file in use.
Thanks & Regards,
Priyank

Hi Priyank,
To know whether the memory is protected or not, try ISP->Erase Flash (with
"Erase all Flash+Code Rd Prot" checked), and then ISP->Blank Check... Also
make sure that Select Device on the main screen is still showing LPC2138 or
whatever is appropriate!

Hi Ahmad,
I carried out what you told. I did the "Erase all Flash+Code Rd Prot" >
Erase. But when I did the Blank check, it showed that the Block 0 is still
Not Blank. This I guess means that the memory is protected. Any idea how do
we remove this protection. I saw an option ProtectISP in Flash Magic which
was checked. Has this got to do anything with memory protection? But this
option is not highlighted for me to uncheck it.
I was also going through the Flash Magic manual. Can we use Command Line
Interface for erasing the memory block ?
Thanks,
Priyank

Hi Ahmad,
Problem solved.
I got this memory block erased. The problem was with the Oscillator Crystal
Frequency. I had kept it blank. Now I put a 16 MHz frequency. Its now
erasing the blocks completely and flashing the new hex file and the new
changes are observed.
Thanks again for your help.

Priyank
