Eric Wild	a079e2b4ee	firmware: increase reset delay before usb reattach The previous value was way too low and led to reenumeration issues when switching from app to bl because the hosts are fairly lenient and feature long delays until they accept disappearing devices as gone for good instead of ignoring a presuambly flaky usb cable or connection.

Eric Wild	f83d42ce51	firmware: remove usb pullup that dates back to simtrace1 All the parts are DNP and never existed on the simtrace2 with sam3; the sam3 has internal pullups that are part of the usb peripheral. Change-Id: I04a703a2eba6ff1dc64692c089213389d0c1066d	2021-11-01 14:35:14 +01:00
Eric Wild	a7e306f745	firmware: add bootloader update "app" This bl updater can be flashed as app and will update the bootloader and then delete itself before resetting the sam3, so the device will end up in the newly updated dfu bootloader afterwards, without having to press the bootloader button or requring any other manual interaction, ready to receive a new application image. Building the blupdater requires a previously built dfu-flash bootloader bin file that will then be embedded into the app during building.

Eric Wild	7ca68359f3	cardem: fix spurious NULL bytes during transfers The "wait time extension timer" was apparently not being reset during normal tx operations, which led to occasional NULL (0x60) bytes getting injected into transfers, which in turn led to more tx bytes than what the reader side expects... The odd thing is that this was only noticeable with high baud rates, probably due to the very long default WT of 9600 ETU, and even then only because it led to weird ngff modem resets after benign transfers.

Eric Wild	34317c1f32	firmware: proper makefile deps Single threaded evaluation is (assumed to be!) left to right, depth first - but with concurrent make using -j this breaks, because the actual usb string header is generated after the attempt to concurrently compile the code that needs it, since there is no explicit order among the all: dependencies.

Harald Welte	4fe93be725	introduce support for new ngff_cardem board This adds support for the new ngff_cardem board, a board that basically combines a ngff breakout board with a built-in SIMtrace2. Cardem works, but depending on the modem it might need a adjusted ATR to ensure a lower baud rate is used by the modem, high rates might lead to weird power cycling of the card after a few transfers. Trace was also tested and appears to work as expected. Change-Id: Ia96124fbe8a752c98e7fd4096d542a3b2b9bc255	2021-08-02 09:22:46 +00:00
