We can turn partitioning back on with GCC10 because it produces smaller code. 2020-10-20T14:39:32+00:00 Christian Walther cwalther@gmx.ch 2020-10-20T14:37:24+00:00 urn:sha1:1eab0692b50f05f6b8194897386cda7720634fe6 396979a breaks building on macOS: `nproc` is a Linux thing, use a cross-platform alternative. 2020-10-18T01:08:32+00:00 Jeff Epler jepler@gmail.com 2020-10-12T02:01:12+00:00 urn:sha1:396979a67e538da087136ce01dbc4c7a670bf60e This decreases the link time, especially on desktop machines with many CPU cores. However, it does come at a slight cost in binary size, making the flash section about 200 bytes bigger for circuitplayground_express. Before, linking build-circuitplayground_express/firmware.elf takes 8.8s elapsed time, leaving 3128 bytes free in flash. After, linking build-circuitplayground_express/firmware.elf takes 2.8s elapsed time, leaving 2924 bytes free in flash. (-6 seconds, -204 bytes free) If necessary, we can make this per-board or even per-translation to squeeze full builds. 2020-09-21T21:44:26+00:00 Jeff Epler jepler@gmail.com 2020-08-20T16:08:00+00:00 urn:sha1:a2e1867f69ec2d703a9651e5c36a02b0e14dfd9c Tested & working: * Send standard packets * Receive standard packets (1 FIFO, no filter) Interoperation between SAM E54 Xplained running this tree and MicroPython running on STM32F405 Feather with an external transceiver was also tested. Many other aspects of a full implementation are not yet present, such as error detection and recovery. 2020-09-17T23:30:22+00:00 Jeff Epler jepler@gmail.com 2020-09-03T15:00:26+00:00 urn:sha1:45eec5b5a566f049edaff11e8457bc0befe79c60 I recently misdiagnosed a "maybe-uninitialized" diagnostic as a bug in asf4. However, the problem was in our SPI code. A special case for samr21 MCUs was being applied to same54p20a and possibly other D5x/E5x MCUs, since the check was simply for pin PC19 existing at all. Change the check to use the macro PIN_PC19F_SERCOM4_PAD0 which is only defined if special function F of pin PC19 is SERCOM4 PAD0. Reorganize the code a little bit so that brace-matching in editors is not confused by the conditionalized code, including an unrelated change for APA102_SCK's condition. Revert the change to the Makefile that incorrectly attempted to silence the diagnostic. 2020-09-15T03:57:51+00:00 Dan Halbert halbert@adafruit.com 2020-09-15T03:57:51+00:00 urn:sha1:3c6af94fb3964d7d5327c3916f9538303e010646 atmel-samd: add same51, feather_m4_can
