AM3356: PRU Ethernet

Pankaj Suryawanshi

Part Number: AM3356

Hello Community,

I am using custom board based on am3356 in which general purpose ethernet is working, Now I want to use PRU based ethernet ?

Where the changes are required in TI-RTOS ?

Hi Pankaj,

You can refer to the ICSS EMAC driver examples from Processor SDK/PDK -

http://software-dl.ti.com/processor-sdk-rtos/esd/docs/latest/rtos/index_device_drv.html#icss-emac

http://www.ti.com/tool/PROCESSOR-SDK-AM335X

Hi Garrett,

I am referring example of ICSS_EMAC example "NIMU_ICSS_BasicExample_icev2AM335x_wSoCLib_armExampleproject" , But the flow of calls is not as per document( http://software-dl.ti.com/processor-sdk-rtos/esd/docs/latest/rtos/index_device_drv.html#icss-emac

for example. - ICSS_EMAC_testMdioInit(CSL_MPU_PRUSS2_U_MII_MDIO_REGS); // Not available in example but mention in document flow calls.

Pankaj,

It appears the document is not updated accordingly when the code has been changed, please look into the example sour code for better understanding the call flow.

Hi Garrett,

Thanks for the quick response.

Pankaj,

Please check this thread for the high level guidance of porting PRSDK dependency/CSL:

- "By design, CSL APIs follow a consistent style, uniformly across Processor Instruction Set Architecture and are independent of the OS. ", see http://software-dl.ti.com/processor-sdk-rtos/esd/docs/latest/rtos/index_device_drv.html. Alternatively you may refer to the driver implementation from Nucleus-TI-AM335x (https://www.mentor.com/embedded-software/nucleus/readystart/readystart-nucleus-ti/ti-sitara-am335x), for example, in spi_tgt.h from the Nucleus-TI-AM335x, it has similar implementation of register access as in CSL.

#define SPI_ANDOUTBYTE(reg, data) \
((*((UINT8 *)(reg))) = \
(UINT8)(SPI_INBYTE(reg) & (data)))

Garrett
