Windows now ignores the hidden flag, so just nullify the entries to hide depending upon whether or not bootloader install mode is activated. Change-Id: I00d0797e40ea3b5f5d5d8e1243b50cfcdd029bb4
2017-11-21Convert i.MX31 and AMS target to use RTC interruptMichael Sevakis4-9/+84
Instead of checking ticks, set a sticky dirty flag that indicates that the RTC needs to be read. This gives a timely update and more accurate readout without actually reading the RTC until it changes. The implementation should atomically read the flag and clear it. Setting the flag would typically happen in an RTC tick ISR. Change-Id: I6fd325f22845029a485c502c884812d3676026ea
2017-11-21Implement a much more capable vuprintf()Michael Sevakis1-1/+1
New support as well as some buggy support fixed. Still no floating point support if ever that would be desired. Support (*): * Flags: '-', '+', ' ', '#', '0' * Width and precision: 'n', '.n', '*' and '.*' * Length modifiers: 'hh', 'h', 'j', 'l', 'll', 't', 'z' * Radix: 'c', 'd', 'i', 'n', 'o', 'p/P', 's', 'u', 'x/X' (*) Provision exists to switch lesser-used stuff on or off or when certain functionality isn't desired (bootloader?). The compulsory radixes are everything but 'o', 'n', 'p/P' and 'x/X' with length modifiers being optional. The default setup is 'l', 'z', 'c', 'd', 'p/P', 's', 'u', 'x/X'. * Move fdprintf() to its own file. It was in a strange place. * Make callers compatible and fix a couple snprintf() bugs while at it. Could smush it down in size but I'm gonna get over the binsize neurosis and just the let optimizer do its thing. Change-Id: Ibdc613a9b6775802c188b29b9dd46c568c94f7c3

2017-10-26Unify storage threads into oneMichael Sevakis16-1028/+623
* Editing a bunch of drivers' thread routines in order to implement a new feature is tedious. * No matter the number of storage drivers, they share one thread. No extra threads needed for CONFIG_STORAGE_MULTI. * Each has an event callback called by the storage thread. * A default callback is provided to fake sleeping in order to trigger idle callbacks. It could also do other default processing. Changes to it will be part of driver code without editing each one. * Drivers may sleep and wake as they please as long as they give a low pulse on their storage bit to ask to go into sleep mode. Idle callback is called on its behalf and driver immediately put into sleep mode. * Drivers may indicate they are to continue receiving events in USB mode, otherwise they receve nothing until disconnect (they do receive SYS_USB_DISCONNECTED no matter what). * Rework a few things to keep the callback implementation sane and maintainable. ata.c was dreadful with all those bools; make it a state machine and easier to follow. Remove last_user_activity; it has no purpose that isn't served by keeping the disk active through last_disk_activity instead. * Even-out stack sizes partly because of a lack of a decent place to define them by driver or SoC or whatever; it doesn't seem too critical to do that anyway. Many are simply too large while at least one isn't really adequate. They may be individually overridden if necessary (figure out where). The thread uses the greatest size demanded. Newer file code is much more frugal with stack space. I barely see use crack 50% after idle callbacks (usually mid-40s). Card insert/eject doesn't demand much. * No forcing of idle callbacks. If it isn't necessary for one or more non-disk storage types, it really isn't any more necessary for disk storage. Besides, it makes the whole thing easier to implement.

2017-08-27zen/zenxfi: always set EMI frequency to 130MHzAmaury Pouly1-4/+7
The ZEN/X-Fi (STMP3700) don't handle memory frequency scaling really well, for this reason we run it at a fixed frequency. That frequency was previously set to 64Mhz because when the CPU run at its lowest frequency, we set the VDD voltage to 0.975 V and on STMP3700, VDDD=VDDDMEM and this is too low to run EMI at 130Mhz. This is not a good solution because under heavy load, running the EMI at 64Mhz results in frame drops and a sluggish device. Thus we now run the EMI at 130Mhz all the time now. To do so, increase the minimum VDD voltage to 1.275 V. This may result is a decreased battery life on those targets but it will also avoid all sorts of glictches and all the device to truly run at full speed.

2017-03-12Do some housekeeping with fat.h and SECTOR_SIZEMichael Sevakis8-10/+5
Many includes of fat.h are pointless. Some includes are just for SECTOR_SIZE. Add a file 'firmware/include/fs_defines.h' for that and to define tuneable values that were scattered amongst various headers. Remove some local definitions of SECTOR_SIZE since they have to be in agreement with the rest of the fs code anyway.

2017-02-11Improve radio RDS driver and frameworkMichael Sevakis3-50/+23
* Remove unused bits like the radio event and simplify basic radio interface. It can be more self-contained with rds.h only required by radio and tuner code. * Add post-processing to text a-la Silicon Labs AN243. The chip's error correction can only do so much; additional checks are highly recommended. Simply testing for two identical messages in a row is extremely effective and I've never seen corrupted text since doing that, even with mediocre reception. Groups segments must arrive in order, not randomly; logic change only accepts them in order, starting at 0. Time readout was made a bit better but really we'd need to use verbose mode and ensure that no errors were seen during receiving of time and more checks would be need to have a stable PI. The text is the important bit anyway. * Time out of stale text. * Text is no longer updated until a complete group has been received, as is specified in the standard. Perhaps go back to scrolling text lines in the radio screen? * Add proper character conversion to UTF-8. Only the default G0 table for the moment. The other two could be added in. * Add variants "RDS_CFG_PROCESS" and "RDS_CFG_PUSH" to allow the option for processed RDS data to be pushed to the driver and still do proper post-processing (only text conversion for now for the latter).

2017-02-04zen/zenxfi: adjust maximum emi voltageAmaury Pouly1-2/+2
Running at 130MHz is unsafe since on those targets, we disable memory frequency scaling because it is unstable. That leads to situation where cpu is running at 64MHz and VDD is at 1.050V. But on STMP3700, the EMI uses the VDD rail instead of a dedicated VDDMEM rail as on STMP3780. Thus we are essentially running the EMI at 130MHz at 1.050V when the minimum recommened voltage is 1.2V. This commit runs the EMI at 64MHz all the time on the ZEN and ZEN X-Fi which will lead to reduce performance but hopefully increases stability. Change-Id: Ida6c2ec130b1778973e383d7c44a06a6ca8f9268

2017-01-25AMS: Return ascodec to interrupt-based I2C2 driverMichael Sevakis7-133/+583
1. Slightly revised and regularized internal interface. Callback is used for read and write to provide completion signal instead of having two mechanisms. 2. Lower overhead for asynchronous or alterate completion callbacks. We now only init what is required by the transfer. A couple unneeded structure members were also nixed. 3. Fixes a bug that would neglect a semaphore wait if pumping the I2C interrupts in a loop when not in thread state or interrupts are masked. 4. Corrects broken initialization order by defining KDEV_INIT, which makes kernel_init() call kernel_device_init() to initialize additional devices _after_ the kernel, threading and synchronization objects are safe to use. 5. Locking set_cpu_frequency has to be done at the highest level in system.c to ensure the boost counter and the frequency are both set in agreement. Reconcile the locking inteface between PP and AMS (the only two currently using locking there) to keep it clean. Now works fine with voltages in GIT HEAD on my Fuze v2, type 0. Previously, everything crashed and died instantly. action.c calling set_cpu_frequency from a tick was part of it. The rest may have been related to 3. and 4. Honestly, I'm not certain! Testing by Mihail Zenkov indicates it solves our problems. This will get the developer builds running again after the kernel assert code push. Change-Id: Ie245994fb3e318dd5ef48e383ce61fdd977224d4
