Hello Bruce

BSP is intel-x86-64, kernel is v5.4/standard/preempt-rt

[linux-yocto][linux-yocto v5.4/standard/nxp-imx8][PATCH] mmc: core: Apply trim broken quirk to R1J57L

[Xiaolei Wang]

R1J57L mmc chip hw capibility indicates that it supports trim function,
but this function does not work properly, the SDIO bus does not respond,
and the IO has been waiting so set quirks to skip trim

Here is the exact loading order, outlined in target's /etc/modules :

debian@arm:~$ cat /etc/modules
# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

*cdc_ncm*
*cdc_wdm*
*huawei_cdc_ncm*

You need to, using YOCTO recipes, to modify /etc/modules file to look
as shown above, while bitbaking the target.

[yocto] devtool add

[Zoltan Kerenyi Nagy]

Hi Folks,

Is it possible to create a recipe file with devtool?

*devtool add cdc-ncm
https://raw.githubusercontent.com/torvalds/linux/master/drivers/net/usb/cdc_ncm.c
*

There is gonna be a file not found error:


*FileNotFoundError: [Errno 2] No such file or directory: 'cdc_ncm.c'ERROR:
Command 'script -e -q -c "recipetool --color=always create --devtool -o
/tmp/devtoolo5nw4pcb
'https://raw.githubusercontent.com/torvalds/linux/master/drivers/net/usb/cdc_ncm.c
'
 -x /home/zoli/poky/build/workspace/sources/devtoolsrc39q8anfa -N cdc-ncm"
/dev/null' failed*

However when I wget the same source, the c file downloads correctly.

Do you have any idea?

Thanks,

Re: [yocto] insmod - huawei E3372h kernel module

[Zoltan Kerenyi Nagy]

Hi,

I contacted the kernel module (cdc_ncm) developper, and he suggested to 
change/experiment the kernel module load order.

I thought if I specify this way: KERNEL_MODULE_AUTOLOAD += 
"ncm_driver"KERNEL_MODULE_PROBECONF += "ncm_driver"cdc_ncm = "options 
ncm_driver iProduct=USB_Host_Driver_for_Network_Control_Model 
iManufacturer=NCM" KERNEL_MODULE_AUTOLOAD += 
"wmc_device_managment"KERNEL_MODULE_PROBECONF += "wmc_device"cdc_wdm = "options 
wmc_device iProduct=USB_CDC_WCM_Device_Management iManufacturer=WMC" 
KERNEL_MODULE_AUTOLOAD += "lte"KERNEL_MODULE_PROBECONF += "lte"huawei_cdc_ncm = 
"options lte iProduct=E3372h iManufacturer=Huawei"
Than this means the order of loading too. Is there any additional feature in 
Yocto that can interfere and set the exact kernel module loading order?

Thanks,
