Hi there,
I am having issues with my LPC804 (LPC80X ), whenever I initially flash the chip. The chip is no longer able to be detected by the debugger and is unable to be flashed. I have tried on both my custom board and the Development Board Section of the MCU-Link Pro and both have had the same outcome. When programming both with sample files they both worked prior to me programming my custom firmware, hence I am certain it is a software setup issue. From looking at the data sheets and such I believe it might be in the inital bootloader startup that is the issue, as I have removed the system_init(); function and system_lpc804 file from the build with the reset handler branching straight to main. Other than this I am unable to see what could be causing this issue and need some assistance.
My reset handler looks like this:
/* Reset Handler */
.thumb_func
.align 2
.weak Reset_Handler
.type Reset_Handler, %function
Reset_Handler:
ldr r0,=__main
bx r0
.pool
.size Reset_Handler, . - Reset_Handler
