[ECOS] System crashes when executed from ROM

[Chandrasekhar G]

Hi,

    We are trying to execute an application from ROM.  It works perfectly from
RAM.  But with ROM it crashes on entering certain routines.  The routines do
some IO on serial port using cyg_io_read and cyg_io_write and sprintf and
sscanf functions.  Can anybody suggest possible
reasons for this beheavior?

Thank you
