Actually before the first error i got some errors which i ignored and
continued...
i got errors like:
"xxx.c line169, Upload the database First. reset then push the HOTSYNC"
Then i got the error 1)"*** just read from memory location 0x00000006, which
is in low memory."
and when i continue the debugger i get second error
2)"*** just read from memory location 0x47121113, causing a bus error."
