About a file programing RGMII register for AndroidKK4.4.2 of MX6-SABRE-SD

[yuuki]

Dear all,

Our customer changed registers of RGMII by using memtool.

memtool -32 0x20e0790=0x000c0000
memtool -32 0x20e0380=0x0001b020
memtool -32 0x20e0384=0x0001b020
memtool -32 0x20e038c=0x0001b020
memtool -32 0x20e0390=0x0001b020
memtool -32 0x20e0394=0x0001b020
memtool -32 0x20e0398=0x0001b020
memtool -32 0x20e0370=0x0001b020
memtool -32 0x20e0374=0x0001b020
memtool -32 0x20e0378=0x0001b020
memtool -32 0x20e037c=0x0001b020
memtool -32 0x20e036c=0x0001b020
memtool -32 0x20e0388=0x0001b020

They want to implement such registers setting to AndroidKK4.4.2.

Which file should these setting be programed by?
Would you teach this file name and the position?

Best Regards,
Yuuki

Dear igor-san,

Thank you for your support.

Our customer wants to set the Ethernet in U-Boot.

Probably, I think that it is set at the following.
bootable/bootloader/uboot-imx/drivers/net/phy

And I think that it is necessary to add a program file of the PHY that they use into this folder.

Is my understanding right?

Best Regards,
Yuuki

Hi yuuki

yes you are right, one can check ../drivers/net//mxc_fec.c

also one can look at appnote AN4173

Best regards
