Using the same test code as above, it's failing during a division, on the line:</SPAN><BR /><BR /><TABLE border="1"><TBODY><TR><TD bgcolor="#cacaca"> <PRE>divisor = ((uint64_t)uClk &lt;&lt; 28)*m / (baudrate*(m+d));</PRE> </TD></TR></TBODY></TABLE><BR /><BR /><SPAN>In uart_set_divisors. The exact assembly line is:</SPAN><BR /><BR /><TABLE border="1"><TBODY><TR><TD bgcolor="#cacaca"> <PRE>str r1, [r0, r0]</PRE> </TD></TR></TBODY></TABLE><BR /><BR /><SPAN>(At least when that line is highlighted and I click "step" it goes to the HardFault_Handler, which seems to me means that line is the problem).</SPAN><BR /><BR /><SPAN>r1 = r0 = 0. So I guess it's trying to write to address 0, which obviously isn't allowed. The actual piece of code trying to execute this command line is in __udivdi3, which I guess is in one of the toolchain libraries. I guess one possible solution would be to avoid 64-bit divisions?</SPAN><BR /><BR /><BR /><SPAN>For reference, here's lpc177x_8x_uart.c:</SPAN><BR /><BR /><TABLE border="1"><TBODY><TR><TD bgcolor="#cacaca"> <PRE>/********************************************************************** * $Id$&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; lpc177x_8x_uart.c&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 2011-06-02 *//** * @file&nbsp;&nbsp;&nbsp;&nbsp; lpc177x_8x_uart.c * @brief&nbsp;&nbsp;&nbsp; Contains all functions support for UART firmware library *&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; on LPC177x_8x * @version&nbsp; 1.0 * @date&nbsp;&nbsp;&nbsp;&nbsp; 02.

The issue was my linker command line not including "-mcpu=cortex-m3 -mthumb". This was causing GCC to link in the ARM version of libgcc.a instead of the Thumb version. Since the Cortex M3 can't execute ARM instructions, this caused the issues I was experiencing.</SPAN><BR /><BR /><BR /><SPAN>I'm trying to get the MCI and UARTs working on my LPC1778 board. The board is one I designed and built myself, and physically it seems to function fine. I can use timers and toggle GPIOs, but am getting some really weird behavior with trying to configure the UARTs and MCI.</SPAN><BR /><BR /><SPAN>I'm using GCC-ARM-Embedded 4.8-2014-q3-update (also tried with 4.8-2013-q4 and 4.6-2012-something) under Linux, with no IDE (just a Makefile and lpc21isp to program with a USB-serial adapter).</SPAN><BR /><BR /><SPAN>Here's what happens: I try to initialize the UART, and it just... freezes during the UART_Init call (more specifically, in the uart_set_divisors function within that call).
