Hi,
Based on the SDK version 10.01, I successfully ran the vision_apps demo.
However, I have 3 questions:
1. If I modify the "serdes_ln_ctrl" in k3-j721e-evm-ethfw.dtso, after run the command "source ./vision_apps_init.sh", MCU2_0 failed to start successfully. I found some logs missed compared to before modify.
Modify as below:
&serdes_ln_ctrl {
idle-states = <J721E_SERDES0_LANE0_QSGMII_LANE1>, <J721E_SERDES0_LANE1_QSGMII_LANE2>,
// <J721E_SERDES0_LANE0_PCIE0_LANE0>, <J721E_SERDES0_LANE1_QSGMII_LANE2>,
<J721E_SERDES1_LANE0_USB3_1_SWAP>, <J721E_SERDES1_LANE1_USB3_1>,
<J721E_SERDES2_LANE0_PCIE2_LANE0>, <J721E_SERDES2_LANE1_PCIE2_LANE1>,
<J721E_SERDES3_LANE0_IP1_UNUSED>, <J721E_SERDES3_LANE1_USB3_0>,
<J721E_SERDES4_LANE0_QSGMII_LANE5>, <J721E_SERDES4_LANE1_QSGMII_LANE6>,
<J721E_SERDES4_LANE2_QSGMII_LANE7>, <J721E_SERDES4_LANE3_QSGMII_LANE8>;
};
Logs missing after modify:

2. If I modify some value in k3-j721e-rtos-memory-map.dtsi, remote cores also cannot boot successfully.
Modify as below:
vision_apps_main_r5fss0_core0_memory_region: vision-apps-r5f-memory@a2100000 {
compatible = "shared-dma-pool";
reg = <0x00 0xa2100000 0x00 0x00f00000>; // from 0x01f00000 to 0x00f00000
no-map;
};
vision_apps_main_r5fss0_core1_dma_memory_region: vision-apps-r5f-dma-memory@a3000000 {
compatible = "shared-dma-pool";
reg = <0x00 0xa3000000 0x00 0x00100000>; // from 0xa5000000 to 0xa4000000
no-map;
};
Logs as below:

3. I know that ETHFW can be disabled in vision_apps, but I would like to ask if it is possible to completely remove the ETHFW-related configurations and code, other than just disabling it?
Looking forward to your reply, Thanks!
