Harald Welte 7e4390f181 qmod: wwan_led.c: Fix handling of LED for second Modem 2017-05-05 20:58:53 +02:00
Harald Welte 9164a6d335 qmod: Disable various console commands on ST34 
A number of commands related to the USB hub and the EEPROM are only
available on ST12, but not on ST34.  Let's remove them if not
applicable.

Harald Welte 2cbc9b29f3 use same USB Product ID for DFU and runtime mode 
This was introduced for interoperability with operating systems that
might prefer such setup (I heard that Windows prefers this about a
decade ago, but I don't have any personal experience with it).

However, using different VID/PID between DFU and RT breaks usability of
dfu-util, and I really think this matters much more to our users and
developers.

Harald Welte 8196e4d1be remove old python userspace code 
the USB protocol is changing fundamentally anyway, and APDU handling for
card emulation is inside the device, so the old code is incompatible
anyway.

Harald Welte 601e0d3e35 update + split README into general and firmware-specific part 2017-03-08 15:33:33 +01:00
Harald Welte 3d4869cbb4 add missing usbstring.c 2017-03-07 15:51:49 +01:00
Harald Welte 353330dcc7 qmod: Fix polarity of SPDT switch 
the default boot state should be to use the local SIM, until the user
changes it (currently only possible via entering '!' or '@' on the
serial console).  The code so far had this completely inverted.

Harald Welte 3bbaba0090 DFU: Disable LED blinking code 
Something odd is happening that breaks DFU mode if we blink.  Let's
remove this feature for now.

Harald Welte e8869fb8ff DFU: Resolve DFU runtime descriptor dynamically from descriptors 
We cannoy simply use the DFU runtime descriptor of the DFU mode, but we
have to use the descriptor of the specific currently-selected runtime
configuration.  Let's iterate over the descriptors of a configuration
and find the DFU runtime descriptor in it.

Harald Welte 5b108d8cf0 DFU: initialize g_dfu during real power up 
At power-up we need to initialize g_dfu once, to ensure a consistent
state.  Afterwards we want to keep it across (software) reset, but on
power-up the memory would otherwise be filled with random data, causing
issues with detection of DFU/Runtime switching.

Harald Welte 96065cacd7 add simtrace2-list to .gitignore 2017-03-06 21:05:44 +01:00
Harald Welte 1892fc1d7c add udev rules for all (currently) supported devices 2017-03-06 21:03:41 +01:00
Harald Welte 822d66ef69 simtrace2-remsim: Improve support for many interfaces + devices 
Rather than using the first available interface on the first available
device, we now have a "simtrace2-list" program that lists all compatible
interfaces on all configurations of all devices on the system
 2017-03-06 21:03:31 +01:00
Harald Welte 62bfd8a7a9 simtrace2-remsim: Document and add longopts for UDP forwarding 2017-03-06 20:56:14 +01:00
Harald Welte b170ea90d3 host: fix some compiler warnings (now that we have -Wall) 2017-03-06 18:59:41 +01:00
Harald Welte dea64cb746 host: Add "-Wall -g" CFLAGS to get compiler warnings 2017-03-06 18:57:08 +01:00
Harald Welte 2ba03bb9fc simtrace2-remsim: Move away from global variables 
When we want to run multiple instances of the card-emulator (e.g. for
multi-modem/multi-card versions of the hardware), the code shouldn't be
using any global variables but have them per-instance.
 2017-03-06 18:57:01 +01:00
Harald Welte abba8a8d85 LED: Introduce LED blinking pattern code 
It might be useful to display some different blinking patterns to
indicate specific system state (such as DFU mode vs. regular firmware)
 2017-03-06 16:58:00 +01:00
Harald Welte 054216d94d usb: Use different SubClass values for card-emulation and sniffer 
This way, host code can dynamically detect which interface supports
which functionality.

The related #defines should be moved to a header file that's shared with
the host application code.
 2017-03-06 10:07:17 +01:00
Harald Welte eab7e456fe USB: Don't specify Class/Subclass 0xff at device level 
Actually, at device level we want to specify 0, so we can select
individual Class/Subclass values at Interface values.

Table 9-8 of the USB2 Specification is quite clear about this.
 2017-03-06 10:04:56 +01:00
Harald Welte 495a67da7d usb: consistently use named structure initializers 2017-03-06 09:55:37 +01:00
Harald Welte 912b183b29 qmod: Use different Interface Strings for Modem1+2 / Modem 3+4 
This makes it obvious in 'lsusb' and to other software on the USB host
which interface is for which of the modems.
 2017-03-06 09:28:13 +01:00
Harald Welte 809e5840f9 qmod: Add code to switch between physical and virtual SIM 2017-03-06 09:16:40 +01:00
Harald Welte 0a8306ec69 add gnumeric spreadsheet with GPIO/Pin assignments of all boards 
This software is supposed to support a SIMTRACE1 with SAM#, as well
ast the OWHW and QMOD hardware.  Let's compare the GPIO/Pin assignments
of the SAM3 in one shared spreadsheet.
 2017-03-05 22:17:28 +01:00
Harald Welte 2bff7cd9c2 tc_etu: Don't confiugre unused TIOA pin of TC0 + TC2 
When initializing the TC blocks, let's only configure the GPIO pins TCLK
and TIOB, and not the unused TIOA pin.  That pin is actually used for
(separate) different functions in both qmod and owhw.
 2017-03-05 22:15:54 +01:00
Harald Welte 705e899e5f qmod: (re)activate USB port remapping. 
The port mapping is now as follows:

* port 1: ST12
* port 2: modem 1
* port 3: modem 2
* port 4: ST34
* port 5: modem 3
* port 6: modem 4
* port 7: daisy-chaining port

Harald Welte c6e482d581 qmod eeprom/i2c: Re-start watchdog while slow bit-banging 2017-03-05 16:24:29 +01:00
Harald Welte 1776997f8a remove old 'notes' file with german textaul notes 2017-03-05 13:30:32 +01:00
Harald Welte 596e666fa0 fix symlink that caused host programs to not build 2017-03-05 13:28:32 +01:00
Harald Welte 2363fa0327 Generate USB Strings from apps/*/usb_strings.txt files at compile time 
This way we can skip the manually-crafted USB string definitions in the
dfu_desc.c and usb.c files.

Harald Welte 1405100dff DFU: Introduce board/app-specific override for booting in DFU mode 
Using the USBDFU_OverrideEnterDFU() function, a board/application can
define extra conditions when the system should boot in DFU mode, even if
it was not explicitly switched to DFU mode from the application.

The app/dfu/main.c uses this mechanism to boot into DFU mode if the
stack + reset vector addresses are not plausible (i.e. some random junk
appears to be flashed in the application partition) or if the user
places a jumper accross the RxD+TxD lines of the debug UART.  The idea
is that the system can be recovered by placing this jumper and then
re-installing the application from DFU.

Harald Welte 7214b4747f Make sure to print CPU Reset Cause when starting the software 2017-03-03 19:02:09 +01:00
Harald Welte 45ebe4591a Enable Watchdog (500ms) 2017-03-03 19:01:53 +01:00
Harald Welte aaba4af46c Use Supply Controller to avoid running SAM3 on voltages lower than 3.0V 
Sometimes there is some leakage current via some I/O that's sufficient
to power up the  SAM3S.  Use the supply monitor to make sure the CPU
will be reset (and kept in reset) if the supply voltage is below 3.0V.
 2017-03-03 18:48:13 +01:00
Harald Welte 3ecbf678db only simtrace is bus-powered, SAM3 on qmod + owhw are self-powered 2017-03-03 02:10:34 +01:00
Harald Welte 8adf0ac2ce DFU app: call into board_main_top() for qmod related initialization 2017-03-03 01:52:34 +01:00
Harald Welte f415d7163b Call USBD_Disconnect before software-triggered CPU reset 
This makes sure that we'll re-enumerate on the USB, as a CPU reset
apparently doesn't automatically release the pull-up and notify the hub
that we were gone?
 2017-03-03 01:51:43 +01:00
Harald Welte ec0837c463 change from \r\n (CRLF) to \n\r (LFCR) 
For some strange reason my output is garbled in both the 'screen' and
'cu' teerminal programs and 'raw' terminal (stty) mode.  I fail to
understand why, but let's simply adjust the code as needed for now.
 2017-03-03 01:33:24 +01:00
Harald Welte 0de99cd069 DFU: String descriptors for DFU alt-interfaces 
they are only shown in DFU mode for now, until we find a way to export
them over to the runtime.

Harald Welte ac4f66e5d1 DFU: Set 10ms bwPollTimeout (lowest possible as per spec) 2017-03-03 01:13:34 +01:00
Harald Welte 91fc40240e DFU: make sure to properly initialize g_dfu pointer before using it 2017-03-03 01:05:22 +01:00
Harald Welte b04f4f0ee8 DFU Runtime: Add missing return after handling USB standard requests 
the same as 479e97e338 but this time for
the runtime, not for DFU.

Harald Welte e8eea29cf6 dfu: fix cosmetic issue in debug message 2017-03-03 00:35:51 +01:00
Harald Welte d1e963479e DFU: fix transitions between runtime and DFU mode 
we now always go through a processor reset to avoid any state that might
be persistent/left-over during the switch.
