Hello,

I am facing some issue when trying to access the ROM and execute the Power Profile API on LPC812.

I reach directly the hardfault handler, but the ROm is clocked.

Did some one has an idea of what is happening?

Thank you for your help.

Antoine

part of my code is here:

LPC_SYSCON->SYSAHBCLKCTRL |= 0x2; // enable ROM
LPC_SYSCON->SYSPLLCLKSEL = 0x0;   // IRC as PLL clock source
LPC_SYSCON->MAINCLKSEL |= 0x1;     // set main clock source as PLL input clock
LPC_SYSCON->SYSAHBCLKDIV |= 0x1;   // AHB CLK DIV set to 1

command[0] = 12000;
command[1] = 30000;
command[2] = CPU_FREQ_EQU;
command[3] = 0;
(*rom)->pWRD->set_pll(command, result);
while(result[0]!=0)
{}
