79396b1777 lib/usb.c (open_usb): Stupid beginner's mistake: wrong operator precedence due
to missing parentheses in device selection caused it to just pick the first
device it found.

5ce904b20f Introduce PLATFORM_ENTER, replacing the old PLATFORM_SETUP for DFU mode
setup. PLATFORM_SETUP now performs early general platform setup, such as
turning off the watchdog.

- fw/boot/boot.c (main): the first thing we do is to run PLATFORM_SETUP
- fw/boot/boot.c (boot_loader): instead of PLATFORM_SETUP, run
  PLATFORM_ENTER

a77a9a611f lib/usb.c (open_usb): libusb documentation claims that considerable
bureaucracy is needed before operations can be performed. This doesn't
seem to be the case, but let's put the code (commented out) anyway,
since it's been written. (This was done while trying to debug another
problem.)

fd09655773 Requests following a rejected SETUP requests failed too, which sometimes
produces user-visible errors and may confuse implementations. (E.g., when
probing for an unimplemented feature and subsequently being greeted by a
timeout.)

- fw/comon/usb.c (handle_setup): set SOPRDY when answering a request error
  with a stall, according to the example in AN139. This seems to eliminate
  the timeouts observed in requests following after bad requests.
- fw/boot/boot.c (run_payload): described how the host is expected to
  respond to the device resetting its USB stack

bc37839a3a f32xbase didn't build on ancient Gentoo due to missing include.

d1b3966e5a Added timer register values.
- fw/common/regs-f32x.h: common values for TCON, TMOD, and CKCON
- fw/common/regs-f320.h: C8051F320-specific values for TMOD and CKCON

0f1c0ea783 - fw/common/regs-f320.h: include mcs51/C8051F320.h, not mcs51/C8051F326.h 2010-08-23 14:31:33 -03:00

1c7150cce8 Registers and register values are now CPU-specific.
- fw/common/regs.h: split into C8051F326-specific regs-f326.h and shared
  regs-f32x.h
- fw/common/regs-f320.h: C8051F320-specific registers and values

fa7fb48296 Put libraries at end of linker invocation to make it work with local
libraries. Some minor cleanup.

- lib/Makefile.common: introduced LDLIBS to place libraries at the end of
  the $(LD) command line
- lib/Makefile.common: put spaces around assignments
- README: added short name of project to title

2a5850591c version.h is no longer generated and it thus only creates confusion if
we create it when making dependencies.

- fw/common/Makefile.common (depend): don't touch version.h
- fw/common/Makefile.common (version): we build version.c, not version.c

7501137fac Added library for items commonly shared among tools.
- lib/Makefile.common: common makefile rules for USB tools
- include/f32xbase/usb.h, lib/usb.c: library with the common open_usb
  function

sensing.

efdacaf589 Add build rules to simplify platform-specific Makefiles.
- fw/common/Makefile.common: integrated object file specific build rules
  that used to live in fw/boot/
- fw/common/Makefile.common: added section titles
- fw/common/Makefile.common (upload): removed obsolete target

3f5ec8aa9e Use config.h as the main source of configuration data. Fixed some boot.c
glitches.

- fw/boot/boot.c, fw/boot/dfu.c: include config.h for platform defines
- fw/common/Makefile.common: add $(F32XBASE)/fw/common to include search
  path
- fw/boot/boot.c: define dummy for uart_init if no debugging is enabled
- fw/boot/boot.c (PLATFORM_EXIT): typo PLAYFORM_EXIT
- fw/boot/boot.c (run_payload): rename BOOT_SETUP to PLATFORM_SETUP
- fw/boot/dfu.c (device_descriptor): use USB_PRODUCT instead of
  USB_PRODUCT_IDBG_DFU
- fw/boot/config.h: removed for now. Might bring it back later as template.
- fw/boot/version.h: moved to fw/common/
- fw/common/Makefile.system: remove serial setup

fcfaec399a Move platform-specific boot loader configuration into macros.
- fw/boot/boot.c (boot_loader): moved GTA-specific pull-up disable and
  I2C_SDA_PULL enable into macro PLATFORM_SETUP
- fw/boot/boot.c (run_payload): moved GTA-specific pull-up enable and
  I2C_SDA_PULL disable into macro PLATFORM_EXIT
- fw/boot/boot.c (boot_loader): moved GTA-specific I2C_SDA probe into macro
  PLATFORM_TEST
- fw/common/Makefile.common: removed all references to dependencies on
  .target. The caller is now responsible for these.
- fw/boot/dfu.c: don't include idbg/usb-ids.h; USB_VENDOR and USB_PRODUCT
  are now passed via macros
