1. Re: CPU load under heavy traffic
ghouse Jul 14, 2017 12:57 PM (in response to raul.benet@lightblueoptics.com)1 of 1 people found this helpfulraul.benet@lightblueoptics.com the sdio/mmc2 driver is more from iMX BSP and it might be better to post this question on NXP forum. https://community.nxp.com/groups/murata-imx

2. Re: CPU load under heavy traffic
raul.benet@lightblueoptics.com Jul 17, 2017 6:58 AM (in response to ghouse)Our design uses the sdio/mmc driver also to talk to an on-board eMMC, which is where we store all our code and data.
I have no CPU load problem when accessing the eMMC, even if I try to continuously read or write large amounts of data.
Furthermore, I would have hoped that given that we are using a "supported configuation", I wouldn't have to go and talk to NXP myself, but rather Murata/Cypress/NXP would work among themselves to solve this kind of issue.
Have you tried to reproduce my observations on a system at your end (ie: running iperf3 or similar over WiFi and looking at CPU) ? What transfer speed do you observe ? and what CPU load coming from the driver ?
Best regards,
Raul.
