3603dc6218 1-wire: Initialization/uninitialization functions are not use MCU-independent up_ naming. Should use STM32-specific stm32_ naming. These are not globally accessible but only accessible from STM32 board logic. 2016-05-25 17:56:47 -06:00

003c2c737a get I2C working. some more work regarding clocking computation is needed, as is some inhertited 'todo's from the basis code. but it does work with the devices tested so far. 2016-05-25 18:43:37 -05:00

04223a9618 SAMV7: USBHS: Remove disabling of whole usb on suspend 
This fix removes the disabling of the whole USB peripheral on suspend
interrupt. Its enough to freeze the clock instead.

When disabling the whole peripheral, the next wakeup-interrupt comes
up with an disabled clocking. The unfreeze clock has no effect, because
the master clock is disabled. This makes all registers, including the
IDR unwriteable and the IRQ falls in an endless loop blocking the whole
system.

Furthermore the disabling of the peripheral clock prevents hotplugging
or reconnecting the USB.

c41e6d823a Add the up_systemreset interface to the samv7 arch. The approach is slightly different in that: 1) It enables ARCH_HAVE_RESET and allows the user to set if, and for how long, to drive External nRST signal. It also does not contain a default board_reset, as that really should be done in the config's src if CONFIG_BOARDCTL_RESET is defined. 2016-05-23 17:05:02 -06:00

fca329945b This patch ensures that the TWIHS (i2c) hw get's its clock set when the sequence of 
sam_i2cbus_initialize
sam_i2cbus_uninitialize
sam_i2cbus_initialize

Or twi_reset is called.

I found this a while back in the stm32 family, so there may be more arch-es with this sort of bug. I suppose any driver that has the notion of "do not set the freq if it is already set" could be suspect.

8fac871cc9 Adds a JTAG config and ERASE config to Kconfig to set the CCFG_SYSIO SYSIO Pins 
• SYSIO4: PB4 or TDI Assignment
0: TDI function selected.
1: PB4 function selected.
• SYSIO5: PB5 or TDO/TRACESWO Assignment
0: TDO/TRACESWO function selected.
1: PB5 function selected.
• SYSIO6: PB6 or TMS/SWDIO Assignment
0: TMS/SWDIO function selected.
1: PB6 function selected.
• SYSIO7: PB7 or TCK/SWCLK Assignment
0: TCK/SWCLK function selected.
1: PB7 function selected.
• SYSIO12: PB12 or ERASE Assignment
0: ERASE function selected.
1: PB12 function selected.

The thing I did not add is warning or compilation failure, (to save the next guy the hassle), at ALL the driver points that uses the these pins.

I did remove this

  /* To use the USART1 as an USART, the SYSIO Pin4 must be bound to PB4
   * instead of TDI
   */

  uint32_t sysioreg = getreg32(SAM_MATRIX_CCFG_SYSIO);
  sysioreg |= MATRIX_CCFG_SYSIO_SYSIO4;
  putreg32(sysioreg, SAM_MATRIX_CCFG_SYSIO);

in sam_lowputc.c in favor of an #error - because the default is an input TDI and driving it blindly to an output TXD1, would be a contention.
