Is there any way to call LPC1343 ISP mode (mass storage device) throw USB HID using software e.g. C# or Delphi? Currently device working fine with HID (write/read), but what I need to do to activate that mode?

Hello slayo,

Have you already resolve your issue about invoking the ISP mode of LPC1343 through USB HID using c#? If yes, How did you do that?Could you please share it to me. Your response is highly appreciated.

Thanks.

Hi,

Have you looked at the example for auto isp in the code here:

I think it has the pieces you need to get this done.

Hello,

Why is it the bootloader of LPC1343 takes long time to pop up or show up in my disk drive if I use the on-chip rom address on the project. (RAM: 0x10000180 Size:0x1E80 ). Otherwise it shows up directly when I used this address in my project (RAM =0x10000000 Size: 0x2000).
Anyone have an idea about this behavior?

Thanks

This is mentioned in the User Manual:

[I]If the USB ISP mode is entered on power-up (see Section 19.3), the memory is not
initialized, and no user code is executed which could write to this memory location.
Therefore the device times out when first connected to the Windows operating
system, and the MSD disk only appears after a time-out and retry, which takes 45 sec
or longer. A work-around for the time-out issue is not available.[/I]
