Hi,
I am using the demo program C:\ti\TivaWare_C_Series-2.1.3.156\examples\boards\dk-tm4c129x\boot_emac_flash\boot_emac_flash\ compile the flash bootloader for TM4C1294kcpdt, my cmd file:
MEMORY
{
FLASH (RX) : origin = 0x00000000, length = 0x00010000
SRAM (RWX) : origin = 0x20000000, length = 0x00010000
}
SECTIONS
{
GROUP
{
.intvecs
.text
.const
.data
} load = FLASH, run = FLASH, LOAD_START(init_load), RUN_START(init_run), SIZE(init_size)
GROUP
{
.bss
.stack
} run = SRAM, RUN_START(bss_run), RUN_END(bss_end), SIZE(bss_size), RUN_END(__STACK_TOP)
}
after Debug in ccs, the console display an err as follow when i put run button :
CORTEX_M4_1: Can't Run Target CPU: (Error -1268 @ 0x1090001) Device is locked up in Hard Fault or in NMI. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 6.0.407.3)
and the memory browser display from 0 to 00001aa0 the value are all FF, the disassembly window also display all FF, why this happens.
