* Ensure to transmit current req_ctx on RESET/VCC eventsMin Xu2014-11-114-2/+31
| | | | | | | | | | | | | | | | | | When any of the following events occur: * VCC_PHONE off * nRST * RST we tranmsit the current req_ctx, if there is data pending. This ensures that for any successive data, the ATR flag in the next req_ctx containing the data, not in the previous req_ctx. It also ensures that the ATR is aligned at 0 offset in the new req_ctx, which is an assumption the host software makes but the previous code didn't ensure. Furthermore, we introduce a periodic flushing of any pending but incomplete req_ctx.

|
* 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.

* 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.

* 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.

* iso7816_uart: Make sure ATR is separated from normal APDU in all casesHarald Welte2012-05-181-7/+12
| | | | | Prior to this patch, the ATR was not send in a separate USB message for cards that are T=0 only.
* 7816_uart: add comment about f/d calculationHarald Welte2012-05-181-0/+2
|
* simtrace: introduce statisticsv0.5Harald Welte2012-03-233-2/+58
| | | | | | the statistics count various events like overruns, parity errors, missing rctx and can dump those stats via USB as well as on the serial console.
* 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
* simtrace: implement SIM power switching APIHarald Welte2012-03-222-18/+48
| | | | | | | | | there is now a high-level command by which we can swithc the VCC supply of the SIM cards. For some reason, the _PASS variant (passing through the voltage from the phone) doesn't seem to work reliably. It might be that we are draining reverse current throught the LDO once we supply SIM power that way.
* make VCC / card detect more reliableHarald Welte2012-03-221-2/+2

* disable logging of PIO status in PIO interrupt routineHarald Welte2012-03-221-1/+1

* simtrace: Inform host of Fi/Di values (and flag change due to PPS)Harald Welte2012-02-121-0/+5

* simtrace: 7816 UART: Add missing entry in Di tableSylvain Munaut2012-01-261-1/+1
| | | | | | Add missing entry in Fi_table. It's apparently used as '64' in some reader and 'unsupported' in some other. For simtrace I guess we should consider it 64.
* Make sure we don't forward power _and_ supply SIM power at the same timeKevin Redon2011-12-182-1/+20
| | | | | | | | The FPF2005 has no reverse voltage blocker, this is why the 3.3V from the LDO flows back into VCC_PHONE. It even damages the chip (so says the datasheet) I corrected the double power source problem by disabling the LDO (see patch), but still 1.8V does not work and 3.0-3.3V is used. I have to look for other reasons.
* usb: Do not send ZLP when we have filled the windowv0.4Holger Hans Peter Freyther2011-12-143-49/+53
| | | | | | | | | | | | 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.

* dfu: Use {} for possible empty if statement (in case debug is off)Holger Hans Peter Freyther2011-11-101-1/+3

* dfu: The i variable to disable interrupts shadows the outer indexHolger Hans Peter Freyther2011-11-101-3/+3
| | | | | | | | In case ram_app_entry() returns do not reset i to 32, otherwise we will never reset the watchdog. src/dfu/dfu.c:1077:7: warning: declaration of ‘i’ shadows a previous local [-Wshadow] src/dfu/dfu.c:1068:6: warning: shadowed declaration is here [-Wshadow]
* fix linking issue with latest binutils versionsv0.3Bjoern Kerler2011-10-211-1/+1
|
* Fix fi/di calculation for certain mobiles like GT-S770 or HTC RaphaelBjoern Kerler2011-10-211-3/+3
| | | | | There were some mistakes while copying the tables from ISO 7816-3, and also a quite old version of 7816-3 was used.
* SIMTRACE: ISO7816: Deal with ATR that don't have historical bytesv0.2Harald Welte2011-08-161-11/+21
| | | | | In case there are no historical bytes, we immediately transition from the last TD byte into the WAIT_TCK or WAIT_APDU state.
* ISO7816: Properly handle T=0 only cards without TCK in ATRHarald Welte2011-08-161-1/+13
|
* SIMTRACE UART: Reset error status on error related IRQHarald Welte2011-08-151-0/+9
| | | | | This prevents an IRQ-flood after a parity or overrun error, which in turn would cause a watchdog reset.
* simtrace UART: set INACK flag to make sure we ignore any parity errorHarald Welte2011-08-151-3/+3
| | | | | | | As a SIM card tracer, we want to remain completely passive and thus not signal back parity errors with the ISO 7816 NACK. The UART INACK flag does exactly that...
* 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: Fix execution of software that was loaded to RAM via DFUv0.1Harald Welte2011-07-301-8/+17
|
* DFU: Support re-flashing of DFU via DFUHarald Welte2011-07-301-16/+132
| | | | | | | | | As we re-locate the entire sam7dfu program into RAM, we don't need to execute from flash and can thus re-program the DFU partition via the DFU protocol itself (alternate setting '1'). We also implement downloading executable code into RAM using alternate setting '2'. The latter part is not properly executed yet.
* DFU: add third 'alternate configuration' for RAM loadHarald Welte2011-07-308-10/+36
| | | | | This will allow us to load code directly into RAM without going through flash.
* simtrace: add some early spi flash utility routinesHarald Welte2011-07-302-0/+224
| | | | This also adds a new 'main_factory' target for simtrace
* add new RUN_FROM_RAM run-mode for direct DFU-to-RAM supportHarald Welte2011-07-302-1/+3
|
* sam7dfu: update copyright yearsHarald Welte2011-07-291-1/+1
|
* sam7dfu: make sure we can use USB reset to get from DFU -> APPHarald Welte2011-07-291-2/+14
| | | | | | | When we went through a Download -> Manifest cycle, we can switch back to dfuIDLE. However, we need to memorize that manifest had already happened and thus should treat a host-initiated bus reset as trigger to switch back into application mode.
* 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
* dfu: fix EP0 IN trasnfers that are even multiple of 8Harald Welte2011-07-071-4/+14
| | | | | | We have to send a ZLP at the end of such transfers, otherwise the host will time out at the end of the transfer. This resulted in multi-second delays for recognizing the SIMtrace hardware by the USB host.
* simtrace: initialize sniffer mode right after start-upHarald Welte2011-06-301-18/+22
|
* simtrace: switch VCC_SIM into output mode, as we use it to supply VccHarald Welte2011-06-211-2/+8
| | | | | | This is just a temp rework in the 1st generation prototype, as the bus switch has too high resistance for passing throuhg Vcc from the phone to the SIM.
