i want to add a RTL8019 ethernet driver for my board, when i run the
linux, at the init of ethernet, it get
eth0: trigger_send() called with the transmitter busy.
.<6>NETDEV WATCHDOG: eth0: transmit timed out
Hw. address read/write mismap 0
Hw. address read/write mismap 1
Hw. address read/write mismap 2
Hw. address read/write mismap 3
Hw. address read/write mismap 4
Hw. address read/write mismap 5
then i check the code and find it's in 8390.c, caused by uncorrect
write of MAC addr, and now i repalce all the inb,outb,inb_p, outb_p
with get_reg and put_reg in the 8390.c.as follow:
static unsigned char get_reg (unsigned int regno)
return (*(volatile unsigned char *) regno);
static void put_reg (unsigned int regno, unsigned char val)
*(volatile unsigned char *) regno = val;
it can run over t he ethernet init, and it also can mount nfs root
fs, it can ping and responding to ping, and also can do copy,delete in
the nfs root.
but when i run application in nfs root, it get message as follow,
and hang on it
"nfs: server 192.168.81.142 not responding, still trying"
does someone have any idea of this situation?
thanks for any hints
