SOLVED : User error : RTFM.

That bootloader requires a speed of 100k rather than the 125k I was attempting.

Everything is OK now.

Thanks for your help.

Could you please point me at a working example / documentation for using the .NET libraries to program over CAN.

The following code produces the Error : Operation Failed. reading signature (ERROR_CMD)

Code Select Expand

ESA.FlashMagic.ARMCAN.FlashMagicARMCAN Flash = new ESA.FlashMagic.ARMCAN.FlashMagicARMCAN();
            Flash.SelectDebugMode(ESA.FlashMagic.Common.DebugModes.ON, "C:/Data/FMdebug.fmd");           
            ESA.FlashMagic.Common.CANOptions opt = new ESA.FlashMagic.Common.CANOptions();

            opt.selecteddevice = ESA.FlashMagic.Common.Devices.LPC11C14301CAN;
            opt.interfacetype = ESA.FlashMagic.Common.CANInterfaces.PEAKUSB;
            opt.nodeid = 0x7D;
            opt.sdotimeout = 1000;
            opt.baudrate = 125;

            int n = 0;
            try
            {
                n = Flash.Connect(opt);
                string s = Flash.ReadSignature();
                MessageBox.Show(s);
            }
            catch (ESA.FlashMagic.Common.FMException Exc)
            {
                MessageBox.Show(Exc.ToString(), Application.ProductName, MessageBoxButtons.OK, MessageBoxIcon.Error);
            }
            if (n != 0)
            {
                Flash.Disconnect();

The standalone FM gui connects and reads the device signature, so the hardware seems OK.

Any guidance gratefully received.

All these issues have been resolved in V5.92.

Many thanks for your help Andy,

Sent a second copy from a different address.

Debug file emailed to "support" on 5th October

Many Thanks,

I can now successfully erase the device, but the programming step still fails

The file successfully loads using the GUI, so I know it's good.

I can use FlashMagic V5.91 GUI to successfully program my LPC11C14/301 via a PCAN USB.

I am struggling to get a working script to program it on the command line.

"Save Command Line Directives" gives me the following script:

Code Select Expand

COM(0, 9600)
DEVICE(LPC11C14/301 CAN, 0.000000)
ERASEUSED(C:\Firmware\Luci\Cortex\Luci_Cortex_V1_01.hex, PROTECTISP)
HEXFILE(C:\Firmware\Luci\Cortex\Luci_Cortex_V1_01.hex, NOCHECKSUMS, NOFILL, PROTECTISP)

Line 1 fails (not surprisingly) so I deleted it.
Line 2 fails with "unknown device", so I deleted the whitespace before "CAN".

This gives me the following script:

Code Select Expand

DEVICE(LPC11C14/301CAN, 12.000000)
ERASEUSED(C:\Firmware\Luci\Cortex\Luci_Cortex_V1_01.hex, PROTECTISP)
HEXFILE(C:\Firmware\Luci\Cortex\Luci_Cortex_V1_01.hex, NOCHECKSUMS, NOFILL, PROTECTISP)

I now get "Connection failed: comms error".

Is there an undocumented command to set up the CAN communication parameters?

Any help gratefully received,
