I updated the Image Vector Table and the DCD in my code and loaded to flash. After that I am not able to hold the CPU in reset using a debugger. And because of that, I am not able to reflash,......
CPU: iMX53
Flash: External NOR Flash
Image Vec table Entries:
const struct ivt input_ivt ={
0xD1, 0x00, 0x20, 0x40, //Header identifying the type of data structure (0xD1), its size (0x0020 = 32 bytes), HAB version (0x40). i.MX53 uses D100 2040h.
(hab_image_entry_f)main, //Address of main(), which is the "Application" in the BIOS case
NULL, //Reserved and should be zero.
NULL, //Absolute address of the image Device Configuration Table (DCD). The DCD is optional, so this field may be set to NULL, if no DCD is required.
&boot_data, //Absolute address of the Boot Data structure
&input_ivt,
NULL,
0x00000000
};
boot_data_t boot_data = {
(uint32_t) &__bios_start,
(uint32_t) 60000,
0
};
I have confirmed that the ivt appears at 0x1000 offset from the Flash base address
Can someone help me figure this one out?
