[ECOS] hal_diag files

[Tristan CORCELLE]

Hi all,

In the most of files "hal_diag.c", there is:

typedef struct {
    cyg_uint8* base;
    cyg_int32 msec_timeout;
    int isr_vector;
} channel_data_t;

Can anybody tell me where "base" is defined ?

Thanks in advance

Tristan

There is typically a static table in the driver file which initializes
this structure.  For example, in the SA11x0 driver:
    
    static channel_data_t ser_channels[] = {
    #if CYGHWR_HAL_ARM_SA11X0_UART1 != 0
        { (volatile struct sa11x0_serial*)SA11X0_UART1_BASE, 1000, 
          CYGNUM_HAL_INTERRUPT_UART1, CYGNUM_HAL_VIRTUAL_VECTOR_CONSOLE_CHANNEL_BAUD },
    #endif
    #if CYGHWR_HAL_ARM_SA11X0_UART3 != 0
        { (volatile struct sa11x0_serial*)SA11X0_UART3_BASE, 1000, 
          CYGNUM_HAL_INTERRUPT_UART3, CYGNUM_HAL_VIRTUAL_VECTOR_CONSOLE_CHANNEL_BAUD },
    #endif
    };

In this case, "base" is SA11X0_UART1_BASE which is defined in one of the
platform HAL include files.
