[En-Nut-Discussion] Ethernut 1.3H problem with Ethernet and external RAM

[Ayman Hendawy]

Dears,

Recently I replaced the ATMEL128 with new one, but I get a problem that the
Basemon bootloader can't see my Ethernet chip nor External RAM, the out on
serial port as following:

BaseMon 4.1.2
Nut/OS 3.5.0.0
Compiled by AVRGCC for ATmega128
Baudrate select = 95
External RAM Test... 0 bytes
Banked RAM Test... none
Serial FLASH... 0 bytes
Detecting NIC... none
I/O Port Test... OK

Press any of the following keys:
E - Ethernet controller read/write
J - Jump to bootloader
S - SRAM read/write

The Yellow led is off, and Green led is sold on.

The fuses are as following:
lfuse: 0x3f
hfuse: 0x82
eFuse:0xff

When I used the test code at
http://www.ethernut.de/en/hardware/enut1/index.html ,
www.ethernut.de/en/hardware/enut1/testrtl10.zip
I get the following:

101 RTL8019AS Test 1.0
104 Discovered
100 Write OK
100 Config OK
102 EEPROM emulation OK
101 Re-discovered

122 Loopback 2 OK
123 Loopback 3 OK
130 IRQ OK
499 NIC OK
100 Ready for ping 192.168.192.254 (MAC 00:06:98:F0:11:23)

100 No ARP request

100 Rx[0x21]: OK PHY

But I can't ping it !

I don't know what is the problem, any suggestions

Thanks

Hi Ayman,

Sorry to hear about your bad luck with the Ethernut.

Looks completely wrong to me. The chip is still in ATmega103 mode.
Interesting, I didn't expect Basemon and testrtl running on this chip.

This page provides more infos

http://www.ethernut.de/en/isp/fuses.html

Unfortunately it is based on the old uisp tool. I also found

http://eecs.oregonstate.edu/~traylor/ece473/lectures/fuses.pdf

Probably because your PC is in a different network.

Regards,

Harald

Dear Harald,

Thanks for your help,
The link you have sent to me, http://www.ethernut.de/en/isp/fuses.html, say
that the correct fuses setting are as following:
Ethernut Factory Settings

We can call uisp on the command line to read the fuses. Again the following
parameters are for the SP Duo connected to the first serial port.

# uisp -dprog=stk500 -dserial=/dev/ttyS0 -dspeed=115200 -dpart=atmega128
--rd_fuses
Firmware Version: 49.48
Atmel AVR ATmega128 is found.
Fuse Low Byte = 0x3f
Fuse High Byte = 0x83
Fuse Extended Byte = 0xff
Calibration Byte = 0x00 -- Read Only
Lock Bits = 0xff
BLB12 -> 1
BLB11 -> 1
BLB02 -> 1
BLB01 -> 1
LB2 -> 1
LB1 -> 1

which mean that my fuses are correct and for hfuse I but it 0x82 for the
bootloader, this is also mentioned in the above link,
I also try to make it 0x83 but nothing happened, also the atmega 103
compatibility is disabled, I'm sure , and you can check it by your self.

I don't know, do you have another suggestions.

Thanks
