LPC2xxx / LPC 2148 FAILED TO AUTOBAUD
« Last post by nimish on October 15, 2016, 10:55:00 pm »
I was hoping you could help me. I am using the following:

Board: LPC 2148
Software: Flash Magic (latest version on the website)
USB to serial converter: From Nex Robotics (uses FT232RL).

Flash Magic returns a "failed to autobaud" error while copying the hex file to the board. It gives the same error even while reading the device signature.

This is the product I am using for USB to serial conversion. The development board and the converter are both from this vendor. I downloaded the driver from the link given on the page.
http://www.nex-robotics.com/products/usb-interfacing/usb-to-rs-232-converter.html

I have tried reinstalling the driver as well as changing the COM port number to a different unused one. Nothing seems to work. The COM port does appear in the device manager.

I tried using Realterm to see if I get a response by sending alphabets, but none appear on the screen. The TXD light does glow on the converter each time I type the alphabet.

A week ago, although I used to get the occasional autobaud error, I still managed to burn a few codes onto the board however now it seems to have stopped working completely. Now, I have no clue where the error lies.

Do respond at the earliest.

I have attached the Flash Magic Debug file.

P89V51Rx2/P89LV51Rx2 / Can't program p89v51RD2FA...AC
« Last post by roniger on October 15, 2016, 11:37:41 am »
Hi,
I've been using the p89v51RD2FN...A0 for some time now, and always managed to program it using flash-magic.
Recently I got several chips ending with AC, which I can't program.
When replacing the chip in the socket to an A0 ending chip, I can program it and work with it fine.
The full chip numbering I have is:
Non working chip:
P89V51RD2FN
FA68-0523
-zG1420 AC
Working chip:
P89V51RD2FN
FA68-0459
-zG0731 A0

Do you guys have a clue?
Is it a malfunction of the chip-series? Or something I am doing wrong?

Thanks

ARM Cortex / Enable Code Read Protection via command-line
« Last post by thgid on October 12, 2016, 07:05:16 am »
I would like to enable the Code Read Protection feature via command-line on NXP NHS3100 ARM microcontrollers.

It looked like this would be possible via the SECURITY command, and the documentation (FlashMagic GUI and Command Line Manual, Rev 2.05) says "for the ARM devices, bit1 = code read protection".

However, all of the following failed:
SECURITY(1) -> Invalid parameters for SECURITY directive
SECURITY(1,0,0) -> Security bit programming failed: invalid command
SECURITY(1,1,1) -> Security bit programming failed: invalid command

Any idea how this could be done?

You will need to put a scope on the new review of the bathmate RST and P0.14 pins and verify the signals you expect are actually there and look correct. Most likely cause is a hardware issue which only you can track down.

Andy

What scope do you recommend Andy?

Did you make the necessary connections on the board? These are shown in the device database when you select the external flash option?

Yes it was a wiring issue.

Thanks.

Please send screenshots of your Flash Magic settings, and advanced options and photographs of the jumpers on the board.
