USB Firmware upgrade

USB firmware upgrade

Hello,

I am working on the USB firmware upgrade module for LPC2368 (ARM/GCC)

Kindly help me in providing any details regarding this..

Thank you

  • I have build two modules on LPC2368/ARM/GCC
    1. Firmware upgrade: which resides from sector 0 to 2
    2. System firmware: which resides from sector 3 to 7

    The "firmware upgrade" will get the new firmware through the USB and is writing into flash from sector 3 to 7. Once new firmware is written fully with a signature, system is reseted through watchdog timer.
    After reset, control comes first to Firmware upgrade, if the signature and CRC are matched control goes to new firmware.
    The new firmware is working good if it does not have any interrupt related functions, but if any interrupt related function is added, it is not able to get the interrupts.

    kindly suggest, how should i proceed
