typedef Cpsw_Obj* Cpsw_Handle |
CPSW peripheral handle.
void Cpsw_initCfg | ( | EnetPer_Handle | hPer, |
Enet_Type | enetType, | ||
void * | cfg, | ||
uint32_t | cfgSize | ||
) |
Initialize CPSW peripheral's configuration parameters.
Initializes the configuration parameter of the CPSW peripheral.
int32_t Cpsw_open | ( | EnetPer_Handle | hPer, |
Enet_Type | enetType, | ||
uint32_t | instId, | ||
const void * | cfg, | ||
uint32_t | cfgSize | ||
) |
Open and initialize the CPSW Peripheral.
Opens and initializes the CPSW peripheral with the configuration parameters provided by the caller.
hPer | Enet Peripheral handle |
enetType | Enet Peripheral type |
instId | Enet Peripheral instance id |
cfg | Configuration parameters to be initialized. The config is of type Cpsw_Cfg. |
cfgSize | Size of the configuration parameters. It must be the size of Cpsw_Cfg config structure. |
int32_t Cpsw_rejoin | ( | EnetPer_Handle | hPer, |
Enet_Type | enetType, | ||
uint32_t | instId | ||
) |
Rejoin a running CPSW peripheral.
Reopens the CPSW peripheral, but doesn't perform any hardware initialization. This function is expected to be called to attach to a running peripheral.
This is an optional function and could be set to NULL if the peripheral doesn't implement it.
hPer | Enet Peripheral handle |
enetType | Enet Peripheral type |
instId | Enet Peripheral instance id |
void Cpsw_close | ( | EnetPer_Handle | hPer | ) |
Close the CPSW peripheral.
Closes the CPSW peripheral.

uint32_t | cmd, | ||
Enet_IoctlPrms * | prms | ||
) |
Issue an operation on the CPSW peripheral.
Issues a control operation on the CPSW peripheral.
hPer | Enet Peripheral handle |
cmd | IOCTL command Id |
prms | IOCTL parameters |
void Cpsw_poll | ( | EnetPer_Handle | hPer, |
Enet_Event | evt, | ||
const void * | arg, | ||
uint32_t | argSize | ||
) |
Poll for Ethernet events.
The CPSW peripheral currently doesn't provide polling support.
hPer | Enet Peripheral handle |
evt | Event type |
arg | Pointer to the poll argument. This is specific to the poll event type |
argSize | Size of arg |
void Cpsw_periodicTick | ( | EnetPer_Handle | hPer | ) |
Run periodic tick on the CPSW peripheral.
Run PHY periodic tick on the CPSW peripheral. The peripheral driver in turn runs the periodic tick operation on all opened PHYs.
hPer | Enet Peripheral handle |
EnetDma_Handle Cpsw_getDmaHandle | ( | const Enet_Handle | hEnet | ) |
Get DMA driver handle.
Gets a handle to the CPDMA driver.
hEnet | Enet driver handle |
