LPC1768FBD100 MBED-HDK

Hello,

The MBED Development Stamp mbed-005.1 (LPC1768) uses the MBED-IF01 chip with a 16Mbits (2MB) external Flash (AT45DB161D) to "drag and drop" a .bin file.

The MBED HDK uses the LPC11U35FHI33/501 (128kB) chip with no external Flash to achieve the following:

Taken from MBED website: ************************ The CMSIS-DAP interface provides three main functions over a single physical USB connection :

USB Disk “drag and drop” programming - ideal for fast turn around prototyping, or in-field upgradable products Debug interface using the CMSIS-DAP - Provides full debug capability with tools like Keil MDK USB Serial interface between the host computer and the target ************************ My question: Where are the .bin file stored (potentially 512kB .bin file - LPC1768 Application) when using the MBED-HDK solution?

Thanks,

You mean the .bin you want to program the LPC1768 with? It is stored on the external flash chip. This space is shared with for example LocalFileSystem.

Thanks for the quick reply.

Yes, the .bin file that programs the LPC1768 is what I meant. It is stored on the external flash chip on the MBED development stamp.

However, the MBED-HDK design schematic guideline (http://mbed.org/handbook/mbed-HDK) does not include a external flash chip. It only includes a LPC11U35FHI33/501 (128kB).

So I'm not sure where the .bin file that programs the LPC1768 would be stored? How is the LPC1768 programmed using the MBED-HDK?

Thanks, George

The bin is not temporarily stored anywhere when using the hdk interface. The hdk sends it straight to internal flash of the target processor eg the lpc1768. The spec is not clear, but it seems you will also lose the localfile features when using the hdk.

Thanks for the information.

Thanks Wim.

Since there is no localfile feature using the hdk, is there an application that is needed to download the .bin file to program the lpc1768?

Thanks, George

No application needed to program the lpc1768. The lpc11u35 interface will show up as a USB memorystick when you plug it into the host pc. Just drag and drop the bin and it will be flashed into the lpc1768. Note that you do need to install a driver on the pc when you want to use the serial port feature also.
