AMIC110: ICSS cut-through switch questions

Part Number: AMIC110

#1. In C:\ti\pdk_am335x_1_0_15\packages\ti\drv\icss_emac\firmware\icss_switch\docs\ICSS_SWITCH_Firmware_Design_Guide.pdf, how and where to configure the switch cut-through decision point in software?

#2. the PRU ICSS firmware size of C:\ti\pdk_am335x_1_0_15\packages\ti\drv\icss_emac\firmware\icss_switch\bin\am335x\a8host\REV1\icss_switch_PRU0.bin is 28KB, it is reasonable? each AM335x PRU has only 8KB IRAM.

Hi Tony,

Let me discuss with the firmware developer then get back to you.

Tony,

The decision point is not configurable right now. The point was chosen based on protocol requirements, for example Ethernet/IP has different requirements vs HSR/PRP.

The 28KB is the elf file (icss_switch_PRU0.bin) size. The actual program size included is not more than 8KB IRAM.

Regards,

Garrett
