I'm not aware of anything. Have you asked Future Designs? Andy

Last post by jking - May 12, 2020, 11:26:19 AM

Hello,

Can anyone recommend a replacement for the obsolete USB-ICP-LPC2K made by FTDI?  We use flash magic with the USB-ICP-LPC2K dongle to erase the read protect bit on an NXP LPC1787.

Thanks

Use a USB to RS232 cable, such as one from FTDI. Some of those cables are cheap and don't work properly. Put a MAX232 or similar between the cable and microcontroller. I suggest you look at the schematics of some off-the-shelf LPC2000 eval boards.

Hi all,

I will start to use lpc-h2148 arm board.I have it. I wrote program.
I have a few question which I don't know.
I don't have jtag module
I have paralel and serial port on my pc

question 1) I want to upload program to arm board, Could I upload program via USB port on the arm board? ( I did not try it)

question 2) Could I upload program with USB to TTL  only by using TX,RX,GND?
There are 5 pin on the USB to TTL (+5V,TXD,RXD,GND,+3V)

baund rate 9600
I tried like this flashmagic program, but failed (program gave this error code  operation failed. Failed to autobaund)

USB to TTL >>>> LPC2148
TX         >>>> P0.1 RX
RX         >>>> P0.0 TX
GND        >>>> GND

I need your answer and ideas
with best regards,

The hex file determines where the data goes - it contains the addresses. Andy

Is the board still shown in the drop down list in section one?

Did you program it with firmware that disabled SWD? If yes then you won't be able to reprogram it again.

I am a lowly repair tech..(I like my job though) I am loading the frimware and font into an LPC2148 for a small printer...It loads beautifully from Flash Magic. When i try to ,load my file (hex)  called (LOGO) into the LPC 2148 it load, but to the incorrect block...I want block 26 but the logo seems to go to block 25...Can I tell this program where to put the logo file??

Ok, I found the oscilator frequency field has moved to View->Preferences->Hardware.
Unfortunately the import of an old .fms file doesn't fill this field.
