LPC11C24 CAN bootloader

Hi,

I have just started a new project with the LPC11C24 and I have bought an lpcxpresso to play with until the hardware is ready. I want to use the built in bootloader to flash virgin parts over CAN.
I understand that it is not possible to copy the application from the ram to the flash address 0x00000000: How can I flash my application firmware at address 0x00000000?
For testing I tried to download blinky to address 0x0001000 and start execution at 0x00001000. I changed the MCU settings to MFlash32 (rx) : ORIGIN = 0x1000, LENGTH = 0x7000 but after I send 0x1F51,0x01,0x01 blinky does not start.
I don't get errors from the CAN

I am able to use the memory window in lpcxpresso to verify the erasing and flashing was OK.
I was thinking that I have a problem with the image maybe some build setting?
How can I debug the image flashed at 0x1000?

Many thanks!

Why not? Isn't it a CAN ROM bootloader?

Thanks R2,

My mistake I think. I had read the UM the UART Go command, "[FONT=Arial][FONT=Arial][SIZE=2]The command must be used with an address of 0x0000 0200 or greater.[/SIZE][FONT=Times New Roman]" [/FONT][/FONT][/FONT][FONT=Arial][FONT=Arial][FONT=Times New Roman]Is this restriction also true for CAN?[/FONT][/FONT][/FONT]

Thanks again R2,

Everything is OK now. I had an error reading the bin file:o
The Go is working from address 0 via CAN.
I forgot to release P0_1 and P0_3:o

I don't release PIO0_3. Never :)
