Problem with Firmware Update (0246_lpc11u35) on the Seeeduino Arch pro.

The problem is that uploading some bin files on the board with Mbed Compiler doesn't work anymore with my Arch Pro boards. I thing it is a firmware issue. I try to update with the last firmware. But I have some problem to update the last firmware (0246_lpc11u35) on the Seeeduino Arch pro. It say me that I have not enough space to copy the firmware : there is only 43,5 KB of free space and the firmware is 46 KB. Do you know how to fix it ?

There is a test point named `boot` at the bottom of the board. Connect the test point to GND, and then power on the board, it will boot into the on-chip bootloader. At the on-chip bootloader mode, we can update the new firmware. See also https://github.com/Seeed-Studio/Arch_Pro

Thank you for your answer but is it different to holding down the boards reset button and connect the boards USB debug port to the computer ?
