Harald Welte 2819e9c131 wwan_led: Read + report status changes of WWAN LED inputs 2017-02-03 07:49:28 +01:00
Harald Welte 226b40aba4 WIP: bit-banging I2C support for EEPROM access on QMOD 
for now, it just continuously reads the EEPROM bytes and dumps them to
the serial console for testing.

Harald Welte a02b641650 Add support for 'qmod' (quad-modem) board 
You can compile the firmware for this new target using 'make
BOARD=qmod'.

The QMOD differs from simtrace+owhw in terms of low-level
initialization, as it has an external 12MHz clock at XIN, thus bypasses
the main oscillator and needs different PLL configuration.

Harald Welte 7abdb51f8f ringbuffer: Make ring buffer access irq-save 
We have to temporarily disable nterrupts when performing rinbuffer
operations, as the ring buffer is used both from IRQ as well as process
context.

Harald Welte f672e9d63a req_ctx: Convert from hand-coded linked lists to linuxlist.h 
This also removes the actual queuing code from req_ctx, and
leaves this to the caller.  Only tw out of the existing states actually
required the ordering requirement enforced by the qeue, and in the
future we will need to have per-endpoint queues anyway.  Both means it
is better to manage queues outside the req_ctx, and leve that as a pure
memory allocator.

Harald Welte ba0c688103 owhw: Make owhw/board.h the default for now 
I will re-introduce simtrace2 hardware support later

Harald Welte 9d3e38242c initial commit of more code towards card emulation 
I couldn't help but to spend my sunday on working towards card
emulation, including
* various state machines in the target about ISO7816 states
* tc_etu timer import from simtrace1
* req_ctx import from simtrace1 (needs renaming and simplifiation)
* USB protocol description as cardemu_prot.h
* some host-based testing code to test the state machines

The code seems to work fine throughout card reset, sending ATR and
receiving the TPDU header of the first APDU, up to the point where it
marks the TPDU header as to-be-transmitted over th bulk-in endpoint.

Sending the ATR must be done inside the firmware for timing
requirements.

From that point onwards, the host needs to respond at the very least
with a procedure byte, and some indication whether or not the card
emulator should continue to transmit data (card->reader), or receive
data (reader->card).

The code is intentionally not hooked up yet with the USB logic nor with
the UART.  I want host-based testing completed before doing that.

Christina Quast c63da3f6d5 Makefile: Check for already opened ttyUSBx 
If two ttyUSBx interfaces are read from by ts at the same time,
some letters arrive at one terminal and others in the second one.
Therefore only one terminal should be open at all times.

Christina Quast 2b8a18bf3a Sniffer with ringbuf, works SOMETIMES 
* Sniffer uses phone endpoints for communication and the ringbuffer
    routines the phone communication uses
* Most times the Usart1 interrupt is not triggered, and therefore
    no values are recorded
