Migrating to the STM32F405ZGT6

Hi,

I'm trying to utilize Espruino on the larger STM32F405 package, and having some trouble with getting it to even boot. I've been able to successfully compile and load espruino to an STM32F4DISOVERY on a ubuntu box, and I've also got an Espruino board coming from adafruit to play with directly (I want to see how it does as a nice little protocol tester for some of my devices), but the migration to the larger package for a design already in place is just leaving me puzzled.

I believe I've changed the basic required information to what's needed, and didn't see anything that was obvious in the target libraries (although I could be overlooking an HSE adjustment there?).
Main differences:

1. The larger package.
   
2. The board uses a 16Mhz oscillator.
   
3. Some things like the SD card have different connections so I've left them undefined for now.
   
   

I've taken a few bits and pieces from the smartwatch board configuration to account for the speed change, but it looks to need some heavy updating, so I don't know if that was the best move.

Makefile pertinent info

else ifdef T2_STM32F4
EMBEDDED=1
DEFINES += -DUSE_USB_OTG_FS=1
DEFINES+=-DHSE_VALUE=16000000UL
BOARD=T2_STM32F4

PRECOMPILED_OBJS+=$(ROOT)/targetlibs/stm­32f4/lib/startup_stm32f40_41xxx.o
OPTIMIZEFLAGS+=-O3

I checked the generated pin information and it appears to be okay. Some oddities are the pin labels like below though... although below it shows the define as pin 27 and 27? PB10/PB11 are pins 69 and 70. I see the LED defines are labeled as INDEX, so I'm guessing I'm just reading this wrong and these are offsets, not the actual pin numbers. I did a sanity check with the discovery board it's similar, but just in case her's the info:

DEFAULT_CONSOLE_DEVICE              EV_SERIAL3
DEFAULT_CONSOLE_TX_PIN 26/* B10 */
DEFAULT_CONSOLE_RX_PIN 27/* B11 */
DEFAULT_CONSOLE_BAUDRATE 115200

Am I missing something obvious? After a reset I get nothing out of the USB at all. The USB connections are identical to the discovery. I was going to try and remove the 16Mhz oscillator and bump it down to an 8Mhz one just in case but I figured the above should cover that.
