Help with P2020 eTSEC DTS configuration (I *think*)

Hi, I am porting Open Network Linux (ONL) to a bare metal switch (Kuga 7048N - see attached KUGA7048N_HW_SPEC_v03.pdf). The eTSEC NIC works fine in uboot and in the factory-loaded ONIE install/recovery environments.
However, eTSEC NIC *TX* isn't working for my build. Base address reported as 0xe000 whereas it's 0x8000 in (working) ONIE environment. See below ifconfig output:
| root@localhost:~# ifconfig ma1 ma1 Link encap:Ethernet HWaddr 00:30:ab:2e:45:44 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:16853 errors:0 dropped:414 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:2247973 (2.1 MiB) TX bytes:0 (0.0 B) Base address:0xe000 |
The NIC receives packets, as indicated by ifconfig output above and tcpdump output below:
root@localhost:~# tcpdump -i ma1 |
I created DTS (see attached powerpc-delta-kuga7048-r0.dts) by dumping precompiled DTB from uboot (see attached uboot-dts-dump.txt) and editing it to:
- use P2020RDB profile
- replace "interrupts" and "interrupt-map" references (* 0x######## [0x########]) with md dump of memory addresses referenced.
ethtool reports no link detected and speed/duplex unknown. See output below:

I am happy to post output of any other commands. This isn't my area of expertise, but I am happy to do more digging on my own to solve the issue myself. I've just gotten to the point where I'm spinning my wheels, and I'm not sure what question(s) I need to ask to get the answer(s) that I need. Thanks in advance!

Hello,
Very good job, but this error is not the device tree, this is going to driver code or something in the apps that can not be store in that address.
Regards

I fixed it by using the code for /drivers/net/phy/broadcom.c from https://www.uwsg.indiana.edu/hypermail/linux/kernel/0609.1/2317.html
#include <linux/kernel.h> #include <asm/io.h> /* BCM5421S control register */ MODULE_DESCRIPTION("Broadcom PHY driver"); static int bcm5421s_config_aneg(struct phy_device *phydev) /* Write the appropriate value to the PHY reg */ if (err < 0) return err; /* doesn't have phy interrupt */ return 0; static struct phy_driver bcm5421s_driver = { /* Glossy description on Broadcom's site seems to hint that the 5461 static int __init broadcom_init(void) ret = phy_driver_register(&bcm5421s_driver); static void __exit broadcom_exit(void) module_init(broadcom_init); |
