I am using LPC54102xx64 with uVioson MDK 5.22 。
sometimes direct run into ROM ( like ISP mode, but the P0_31 is high), and sometimes run into startup code, and at both situations, most SYSCON registers are 0xAAAA AAAA, and need almost 10 seconds to run one asm line code at signal-step-debug (F11) mode.
Please help me , what happen and how to do?
below is screen snaps runing!!
Today,I found:
some codes wrote on flash are FFFFFF..........
about at 0x40~..... that should be some of vectors table, and at 0x17D~ that should be rt_lib_xxxx entries !!!
Why ? there are errors during download to flash.
but another small program is all OK, can download and can run right.
There are errors for the larger program download, and when debug, direct run to 0x300000B0, that is ROM area.
see attached images.
please help.
