uboot access mac register

longqiluo — Sun, 19 Feb 2017 10:28:24 GMT

hello,We designed board based on the p1023rds . And the etherent part of it is completely refered to the ethernet part of P1023RDS. But I am confusing about MAC register access.could someone tell me how to read/write dtsec1 mac register by uboot cammand？the CCSR baseaddr=0xff600000

Re: uboot access mac register

Use md - memory display command of the u-boot. See md command description of the u-boot on the following page:http://www.denx.de/wiki/view/DULG/UBootCmdGroupMemory#Section_5.9.2.5.

The P1023 dTSEC1 Block base addresses is 0x4E_0000. See the Section 18.3.3 of the P1023 Reference Manual. Look at the dTSEC Ethernet Module Memory Map in the Table 3-8 of the QorIQ Data Path Acceleration Architecture (DPAA) Reference (REV 2):

hello, I don't know what's meaning of the DTSEC1 block base addrss (4e_0000),

but I access DTSEC memory-map register by reading and writing an address

consisting of the CCSR(ff600000) plus the fman block(100000), plus the offset

of specific register to be accessed , as below,. So what is the DTSCE1 block

base address 4e0000 used for ? The dtsec1 still not work ,pleaese analyze for

me=> base ff7e0000Base Address: 0xff7e0000=> md 0 3fff7e0000: 08240101

Offset 0x4e_0000 correct for the P5020/P3041/P2041. The P1023 offset is 0x1E_0000.
