CONFIG_SYS_I2C_INIT_BOARD
|

|
||||
When a board is reset during an i2c bus transfer
|
||||
chips might think that the current transfer is still
|
||||
in progress. On some boards it is possible to access
|
||||
the i2c SCLK line directly, either by using the
|
||||
processor pin as a GPIO or by having a second pin
|
||||
connected to the bus. If this option is defined a
|
||||
custom i2c_init_board() routine in boards/xxx/board.c
|
||||
is run early in the boot sequence.
