63bce97cbd PLATFORM_FATAL_ERRORs are now caught even when they happen in the 
initial JTAG scan that occours during platform_init.

Previously any fatal errors that occoured during this scan caused a
hardfault.

09fbe783c5 f4discovery: Limit clock to 48 MHz and stack 24 kiByte so that code can be compiled unchanged for F401Discovery too. 
TODO: Bump clk up to 84 MHz as soon as libopencm3 supports that speed.

c28350f242 FIX: u{8,16,32} -> uint{8,16,32}_t to be compatible with new library 
The use of u8, u16, u32 has been deprecated in libopencm3.
Update it with standard uint8_t, uint16_t, uint32_t types

43f7e7a3cf Changes to the USBUART to make it less likely to drop characters at higher baud rates. 
USB UART seems to work fine at 115.2Kbps or 230.4Kbps, but starts to drop characters
as the data rate goes higher. This commit changes the usbuart ISR to fill a software
FIFO, and adds a low priority timer interrupt to run deferred processing to drain a
FIFO and send USB CDCACM packets, rather than calling the usb send within the UART
ISR.

Tested on native platform, up to 1.5MBps.

f1ea5ed8f9 F4Discovery: Slow Down GPIO access a little, as off-board SWD otherwise needs _very_ good ground connection. 2013-04-23 13:43:43 -07:00

04624af4e5 f4discovery: Adapt from the "native" file and add or change code where needed 
- stm32_mem.py has problems with erasing the big pages, but dfu-util works
- serial GDB remote server doesn't work. It neither works for the STM32F107,
  so maybe there is a problem with the usbd_f107_driver.
