Gregory Nutt 69c69c45c6 SAMA5: Update from David Sidrane to last RAM function change: Apparently inline functions need to placed into the same RAM section, or they do not get inlined. From David Sidrane 2014-04-04 08:59:39 -06:00
Gregory Nutt 5eeb9f97fc Fix a build error when only USB device tracing is enabled (from David Sidrane). Also an update to the USB tracing document 2014-04-04 08:56:10 -06:00

Gregory Nutt 2efc4d6396 SAMA5: On some hardware, reconfiguring the PLL while executing out of NOR FLASH causes crashes. This was fixed by David Sidrane by implementing RAM functions. The killer code is copied and executed from ISRAM and the crash is avoided. 2014-04-03 16:08:18 -06:00

Gregory Nutt 048230fb94 SAMA5: When booting from SDRAM, don't copy vectors to ISRAM. Instread just set the VBAR register to add address of the vectors in SDRAM 2014-04-03 14:09:11 -06:00
Gregory Nutt c9fc03d52f If LOWVECTORS is selected, then we need to clear the VBAR register. A bootloader may have left the VBAR in an bad state 2014-04-03 13:09:30 -06:00
Gregory Nutt 11c7386dab SAMA5: Make sure the MMU and caches are disabled on power up; flush the vector region D-Cache after copying interrupt vectors; make sure that D-Cache, I-Cache, and TLBs are invalidated after modifying the AXI MATRIX remapping 2014-04-02 16:27:00 -06:00
