SuperCAN v1.0.17

Firmware v0.5.9

bugfixes

• SAME5X boards: fixes M_CAN error handling

  M_CAN reports errors through PSR.LEC and PSR.DLEC. Reading each
  field will result the field to be cleared to 0x7 (no change).

  The previous code interpreted 0x7 to mean that the last proper
  error (0x1-0x6) is still valid. This, however, seems to not be the
  case according to the M_CAN manual v3.3.0, p. 18.

misc

• refactoring to support D5035-51 in SuperDFU
  • remove 'manifest tolerant' RT USB descriptor attributes
  • convert firmware builds to SuperDFU 0.6.1
