Because CT32B1 (P1_1, P1_2 and P1_3) is used by us_ticker.c for wait and ticker function. Since wait/ticker is commonly used by mbed code and I decided CT32B1 of LPC11XX should only be used for this function, not for PwmOut.
P1_6 and P1_7 are used by UART (USBTX/USBRX) and I think they should not be assigned to other function.
Fault is triggered by trying to read LPC_CAN1->IER when the peripheral is powered off. Fixed by checking the power control register before checking the IER register.
While fixing this issue in the various LPC* ports, I noticed a comment
pointing to this mbed forum post which summarizes this bug quite well:
https://mbed.org/forum/bugs-suggestions/topic/4473/
This bug was introduced in the following commit:
2662e105c4
The following code was added to serial_putc() as part of this commit:
uint32_t lsr = obj->uart->LSR;
lsr = lsr;
uint32_t thr = obj->uart->THR;
thr = thr;
As the forum post indicates, this causes the serial_putc() routine to
actually eat an inbound received byte if it exists since reading THR is
really reading the RBR, the Receiver Buffer Register. This code looks
like code that was probably added so that the developer could take a
snapshot of these registers and look at them in the debugger. It
probably got committed in error.
LPC11U24/LPC11U24_301/LPC11U35_401 shared the same startup file for ARM
and uARM toolchains, which is wrong, because the initial SP value is
different for LPC11U24_301. This commit fixes this issue by giving each
target its own startup file.
There were lots of overlaps in the code for LPC810 and LPC812, including
duplicated source files. This commit adds a TARGET_LPC81X_COMMON folder in
both HAL and CMSIS, this folder keeps common code for the targets.
1. Added: GCC_CR toolchain ID for LPC2368. (targets.py)
2. Modified: Startup codes for GCC_ARM and GCC_CR toolchain.
3. Verified: "ticker" and "basic" test program work well, so far.
(Fixed typo.)

A new hooks mechanism (hooks.py) allows various targets to customize
part(s) of the build process. This was implemented to allow generation of
custom binary images for the EA LPC4088 target, but it should be generic
enough to allow other such customizations in the future. For now, only the
'binary' step is hooked in toolchains/arm.py.
