openpcd/firmware/src, branch v0.1 Firmware for the OpenPCD, OpenPICC and SIMtrace hardware https://git.gnumonks.org/cgit/openpcd/atom?h=v0.1 2011-07-30T16:53:43+00:00 DFU: Fix execution of software that was loaded to RAM via DFU 2011-07-30T16:53:43+00:00 Harald Welte laforge@gnumonks.org 2011-07-30T16:53:43+00:00 urn:sha1:1acaecb4cb1de370a4fee692baaf6b41b8d8ec8c DFU: Support re-flashing of DFU via DFU 2011-07-30T00:56:36+00:00 Harald Welte laforge@gnumonks.org 2011-07-30T00:56:36+00:00 urn:sha1:58d958e60c429bd7a2b2d114a4f7a86a65bdacef 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 load 2011-07-30T00:08:36+00:00 Harald Welte laforge@gnumonks.org 2011-07-30T00:08:36+00:00 urn:sha1:e3d1fd9bbdb789196c25bdd5eb7536cda5ba39f3 This will allow us to load code directly into RAM without going through flash. simtrace: add some early spi flash utility routines 2011-07-29T22:39:55+00:00 Harald Welte laforge@gnumonks.org 2011-07-29T22:39:22+00:00 urn:sha1:de0d7e35eed67bab478fda9eee7cb9edb1f34f04 This also adds a new 'main_factory' target for simtrace add new RUN_FROM_RAM run-mode for direct DFU-to-RAM support 2011-07-29T22:37:04+00:00 Harald Welte laforge@gnumonks.org 2011-07-29T22:37:04+00:00 urn:sha1:5a8cd9feca7d0d09aee736ff804be4967828aefd sam7dfu: update copyright years 2011-07-29T21:33:20+00:00 Harald Welte laforge@gnumonks.org 2011-07-29T21:33:20+00:00 urn:sha1:a1e7c0c5efba4eebdb1ed178b5e3604226a1421a sam7dfu: make sure we can use USB reset to get from DFU -> APP 2011-07-29T21:30:00+00:00 Harald Welte laforge@gnumonks.org 2011-07-29T21:30:00+00:00 urn:sha1:d56bb35e907e2d7c4507b7240e36d8b69d272bce 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 data 2011-07-07T15:43:55+00:00 Harald Welte laforge@gnumonks.org 2011-07-07T15:43:55+00:00 urn:sha1:a23eefc6dc5f45498116f69125f6e12f53a81130 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 8 2011-07-07T15:39:32+00:00 Harald Welte laforge@gnumonks.org 2011-07-07T15:39:32+00:00 urn:sha1:fe88b83e80df8be0351ff38ee6a77b855b0cd0a9 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-up 2011-06-30T11:55:00+00:00 Harald Welte laforge@gnumonks.org 2011-06-30T11:55:00+00:00 urn:sha1:30cb576ca5ed5281e997333fd522440faa595565
