* Retrieve + print previous PC from stack to debug wdog/spurious IRQMin Xu2014-11-111-3/+15
| | | | | | | | | | | Retrive previous PC from the stack before entering specific interrupt handler routines. Allow user to trace where interrupt occured: e.g. WatchDog and Spurious interrupt Prior to this change, spurious interrupt would occur so much (observed via gdb/remote debug) so it appears that the board stalled. Once a custom spurious interrupt installed, the code continues after the interrupt instead of re-entering the interrupt.
* change number + qty of small/large req_ctxMin Xu2014-11-112-12/+7

* pcd_enumerate: More complete USB endpoint resettingMin Xu2014-11-111-9/+7
|
* req_ctx: Keep statistic about number of req_ctx in given stateMin Xu2014-11-113-4/+19
| | | | ... and print this from a debug statement.
* usbcmd_generic: Add missing \r to DEBUGP()Min Xu2014-11-111-1/+1
|
* watchdog: print watchdog expiration even in non-debug buildsMin Xu2014-11-111-2/+2
|
* pcd_enumerate: Avoid disabling interrupt during endpoint refillMin Xu2014-11-111-25/+28
| | | | | | | | | The old implementation has a big local_irq_save() / restore() around the endpoint re-fill routine. This disables interrupts for a long time, psossibly causing lost interrupts. The new implementation works around this by disabling the USB (UDP) interrupt only, rather than disabling all interrupts on the system.
* dbgu: make debug routines re-entrantMin Xu2014-11-113-120/+193
|
* req_ctx: Change number of small / large req_ctxMin Xu2014-11-111-1/+5
|
* req_ctx: avoid loop iterations by introducing per-state queuesMin Xu2014-11-112-23/+120
| | | | | | In order to speed up the lookup of req_ctx, we keep per-state queues rather than iterating over all the request contexts that exist again and again.
* change req_ctx sizes large 2048->1000; small 128->270Min Xu2014-11-111-2/+2
|
* req_ctx: Use consistent numeric range for REQ_CTX_STATEMin Xu2014-11-112-21/+24
| | | | | ... which will allow us to check for invalid states by a simple 'greater than' check later on.
* wdt: make sure WDT doesn't fire inadvertentlyHarald Welte2012-03-221-6/+13
| | | | We have to set WDD and WDV to the same value to avoid watchdog errors
* disable logging of PIO status in PIO interrupt routineHarald Welte2012-03-221-1/+1
|
* usb: Do not send ZLP when we have filled the windowv0.4Holger Hans Peter Freyther2011-12-141-25/+29
| | | | | | | | | | | | Only send the ZLP if we send less data than was required/asked for by the host and it is a multiple of the bMaxPacketSize0 (which is hardcoded to 8 right now). This is completing the change done in fe88b83e80df8be0351ff38ee6 to fix SIMtrace attached to OSX and not regress on windows. Introduce another parameter to udp_ep0_send_data to specify the window size (wLength) or if not available the default from USB 2.0 specification.
* DBGU: Print Reset controller Status Register on bootHarald Welte2011-08-151-0/+4
| | | | This helps us to discover _why_ the CPU has been rebooted.
* USB: Add support for the 3rd DFU interface (RAM)Harald Welte2011-08-151-0/+6
|
* DFU: add third 'alternate configuration' for RAM loadHarald Welte2011-07-301-7/+7
| | | | | This will allow us to load code directly into RAM without going through flash.
* add new RUN_FROM_RAM run-mode for direct DFU-to-RAM supportHarald Welte2011-07-301-1/+1
|
* USB driver: use the DFU-provided function to send EP0 dataHarald Welte2011-07-071-48/+1
| | | | | There is no point in replicating the functionality that already exists in the DFU section of the flash
* simtrace: add support for the analog bus switchHarald Welte2011-06-161-1/+1
|
* req_ctx: Increase size of small req_ctx to 128 and have 16 instead of 8Harald Welte2010-11-182-3/+3
| | | | | This is required to deal with bursts in SIM comminication while using the SIMTRACE firmware
