MQX 3.8 (CW10.2)
in BSP: bsp_twrk60f120m Rev #: 3.8 Modified: 1/31/2012
Line 349 appears to have an error and likely should be an OR-EQUAL (|=) instead of EQUAL (=) assignment.
Otherwise the AND-EQUAL (&=) line above it has no function. Without it, it never clears the IREFS and always returns 0x11 and stays clocked by the internal ref clock and throws off the timer calculations.
temp_reg = MCG_C1;
temp_reg &= ~(MCG_C1_CLKS_MASK | MCG_C1_FRDIV_MASK | MCG_C1_IREFS_MASK);
temp_reg = MCG_C1_CLKS(2) | MCG_C1_FRDIV(frdiv_val);
MCG_C1 = temp_reg;
My bsp_cm.c file is dated 12/28/2011.
I installed it 2/29/12 from FSLMQX_3.8.0_TWRK60F120M_PATCH.exe which seems to match the current one in the downloads area.
I have derived a BSP from this one. Is there a list anywhere of changes and corrections for the bsp_twrk60f120m BSP?
