* - we increase the DFU size from 4k to 16k size. This is mainly due to thelaforge2006-09-224-23/+59
| | | | | | | | | | | | | | | | | | | SAM7S128 and SAM7S256 being restricted to 16k lock region size. If we want to lock the bootloader, it has to be 16k aligned. This wastes a lot of memory, since a non-debug DFU implementation fits currently into less than 4k. But anyway, we have lots of flexibility for the future given that amount of space. - The DFU size change introduces also a change in dfu_api location to 0x103fd0 - Allow GETSTATE and GETSTATUS from runtime mode (optional in DFU spec) - Make dfu_status a .data.shared variable, since it is used from GETSTATUS which we already support in runtime mode - do some led switching while flashing via DFU - disable all non-usb/dbgu interrupts when switching to DFU mode - fix interrupt-storm problem when dbgu is used in DFU loader - add missing linker script for SAM7S128 git-svn-id: https://svn.openpcd.org:2342/trunk@218 6dc7ffe9-61d6-0310-9af1-9938baff3ed1
* fix completely broken logic of processing pending outbound packets. We now dolaforge2006-09-221-17/+5
| | | | | | | | | | | | | | | | | | all the req_ctx state changes from within pcd_handler.c and only expose the refill_ep() functions. It's questionable whether we need to keep calling those functions all the time either. Once kicked off, the tx completion interrupts of the UDC will refill the pipe as long as there is data available. So realistically speaking, we'd only need to trigger tx once (and keep triggering until no EBUSY or other error is signalled anymore). Some form of state machine would be fine for doing this, one that registers a timer with the core OS timer (once we have something equivalent to 'struct timer_list'. git-svn-id: https://svn.openpcd.org:2342/trunk@217 6dc7ffe9-61d6-0310-9af1-9938baff3ed1

* Completely separate DFU from application program, we now have a real bootloader.laforge2006-09-137-193/+268
| | | | | | | | | | | | | | DFU occupies 0x00100000 - 0x00100fff in flash, application starts at 0x00101000. DFU also occupies the first couple of bytes in SRAM, application starts at 0x00200024. In order to produce a samba-flashable image, first build dfu.bin by typing 'make -f Makefule.dfu', succeeded by 'make TARGET=... DEBUG=... BOARD=...' and then concatenating the two files together, e.g. cat dfu.bin main_reqa.bin > flash.bin. Actual flashing via DFU is still not operational, but will be implemented next git-svn-id: https://svn.openpcd.org:2342/trunk@194 6dc7ffe9-61d6-0310-9af1-9938baff3ed1
