Hi TI team
we want to use PRU-ICSSG2 ethernet with AM65x SR2.x in u-boot (SDK: TI Linux-RT 07_03_00_08, Board: AM65x SR2.x IDK EVM).
Your Uboot Networking documentation ( https://software-dl.ti.com/processor-sdk-linux-rt/esd/AM65X/07_03_00_08/exports/docs/linux/Foundational_Components/U-Boot/UG-Network.html?highlight=cpsw# ) fits only to AM65x SR1 boards.
I have tried the following u-boot commands, but it fails:
setenv firmware_dir '/lib/firmware/ti-pruss'
setenv ethact pruss2_eth
setenv get_firmware_mmc 'load mmc 1:2 ${loadaddr} ${firmware_dir}/${firmware_file}'
setenv start_icssg2 'rproc start 14; rproc start 15; rproc start 16'
setenv load_icssg2_pru0_fw 'setenv firmware_file am65x-sr2-pru0-prueth-fw.elf; setenv loadaddr 0x89000000; run get_firmware_mmc; rproc load 14 0x89000000 $filesize; rproc start 14'
setenv load_icssg2_rtu0_fw 'setenv firmware_file am65x-sr2-rtu0-prueth-fw.elf; setenv loadaddr 0x8a000000; run get_firmware_mmc; rproc load 15 0x8a000000 $filesize; rproc start 15'
setenv load_icssg2_txpru0_fw 'setenv firmware_file am65x-sr2-txpru0-prueth-fw.elf; setenv loadaddr 0x8b000000; run get_firmware_mmc; rproc load 16 0x8b000000 $filesize; rproc start 16'
setenv init_icssg2 'rproc init; run load_icssg2_pru0_fw; run load_icssg2_rtu0_fw; run load_icssg2_txpru0_fw'
run init_icssg2
run start_icssg2
setenv ipaddr 192.168.0.100
setenv netmask 255.255.255.0
run start_icssg2
ping 192.168.0.10
I get following u-boot outputs:
=> setenv firmware_dir '/lib/firmware/ti-pruss'

What does not fit there yet? Can you please give us a short updated description how to use the PRU-ICSS2 with AM65x SR2.x in u-boot.
