PRU-ICSS-INDUSTRIAL-SW: Configuration related to Firmware from emac driver

Part Number: PRU-ICSS-INDUSTRIAL-SW
Other Parts Discussed in Thread: AM6548

Hi,

I am developing an Ethernet driver for PRU-ICSSG using dual mac firmware for AM6548 chip based on a proprietary RTOS.

I have some queries related to configuration of hardware from PDK code:

The driver open function "emac_open_v5_local" invokes a function "emac_config_icssg_dual_mac_fw". I have seen that it writes some values to the DRAM and SRAM. Is there any guide which I can follow to understand the details about these settings.

I think I would also need to perform similar operation from my Ethernet driver, before writing the dual mac firmware to the IRAM. So, some detailed understanding about these values would be helpful (for example details about the EMAC_PRU_CFG_T structure).

Best Regards,

Debarun

Hi Debarun,

Please check if the design document helps:

HI Garrett,

Thank you for your prompt response.

I have checked the document. There is information about some of the fields like the port queue "7.4.2.2 ICSSG Port Queue Configuration ", but not all the fields.

I have seen that there is a document for "PRU-ICSS Firmware" under "pdk_am65xx_1_0_7\packages\ti\drv\icss_emac\firmware\icss_dualemac\docs\ICSS_DUAL_EMAC_Firmware_Design_Guide.pdf" , but similar document is missing for I"CSS-G Dual EMAC" firmware under "pdk_am65xx_1_0_7\packages\ti\drv\emac\firmware\icss_dualmac". Is there any link from where I can get the ICSS-G DUAL EMAC FIRMWARE DESIGN GUIDE?

Best Regards,

Debarun

Hi Debarun,

We don't have a public available ICSS-G DUAL EMAC FIRMWARE DESIGN GUIDE as the firmware may have significant update in later release.
