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)
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.

Can you please post a recording of the CAN messages on the bus. It looks like the bootloader is not responding.
Andy
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.
