2.If the answer to the first question is affirmative, then I encounter the following issues:
I want to implement a test project to measure the network speed of CR52. So, I modified the "ethernet" example in the Whitebox SDK , and added lwiperf. However, the lwiperf implemented by default in the Whitebox SDK for CR52 is extremely slow. I tried modifying the RSWITCH_MAX_NUM_CHAINS in rswitch.c for experimentation. Although the network speed increased, it still remains very slow. Could you please advise on how to improve the network speed to achieve a level closer to normal speed (on CR52)? Attached are the results of the experiment:
*Linux←→Linux(control group)
*
exp1: Default WhiteBoxSDK Linux←→CR52 lwiperf very slow
exp 2: Increasing the value of TX_RX_RING_SIZE in Rswitch.c improves the speed of the network.
#define TX_RX_RING_SIZE 1024
exp4: Modifying the network's window size yields unreasonable data.
exp 5: Continue to increase TX_RX_RING_SIZE 2560
CR52 fw crash
Hello Max.Sun,
Device driver implemented in Whitebox SDK is for function test so that there is not enough optimization for performance.If you want to know theorytical performance for R-Car S4 SoC, please contact Renesas official support.en-support.renesas.com/dashboard
