Thought my A1 was dead. It isn't, but needs help anyway.

Post by saimo »

Hi all,

After a long time, I finally I managed to get hold of a USB<->RS232 cable, which allowed me to hook my A1 to this machine.
I thought the CPU of my A1 got fried for the second time, but the keyboard lights gave some hopes... and, in fact, the serial output does show that the machine is alive! Still, there is some damage...

Code: Select all

U-Boot 1.1.4 (Mar 16 2006 - 12:23:46), Build: 02/28/06

CPU:   MPC7457 v1.2 @ 1000 MHz
Board: AmigaOne
DRAM:  512 MB
FLASH:  0 kB
*** Warning - bad CRC, using default environment

VGA:   NOT PRESENT
In:    serial
Out:   serial
Err:   serial
SCSI:  Error SCSI Controller (1000,000F) not found
Net:   3Com 3c920c#0
AT Keyboard initialized!
USB:   scanning bus for devices... 1 USB Device(s) found
No Catweasel controller (0xe1594, 0x0001) attached
Bus 0: OK Bus 1: not available  
  Device 0: Model: Maxtor 6Y060L0 Firm: YAR41VW0 Ser#: Y290P84E
            Type: Hard Disk
            Capacity: 58644.1 MB = 57.2 GB (120103200 x 512)
  Device 1: not available
Press any key to interrupt autoboot:  0 
So, it looks the U-Boot FLASHROM is gone... right? (BTW: that would be the second time as well.)
I'll try to take re-seat the chip, but I guess it will be pretty useless.
Any ideas anyone?

EDIT1: it seems it's not possible to send commands, neither by means of the keyboard, nor through the terminal. U-Boot seems stuck.

EDIT2: by pressing madly [ESC] and [ENTER] during boot, I managed to get to access to the prompt! The settings have partially gone - this is all there is:

Code: Select all

bootargs=root=/dev/ram rw ramdisk=4096
bootcmd=menu; run menuboot_cmd
bootdelay=0
baudrate=115200
preboot=
stdout=vga
stdin=ps2kbd
ide_doreset=on
ide_maxbus=2
ide_cd_timeout=30
menucmd=menu
pci_irqa=9
pci_irqa_select=level
pci_irqb=10
pci_irqb_select=level
pci_irqc=11
pci_irqc_select=level
pci_irqd=7
pci_irqd_select=level
bootmethod=boota
boot1=ide
ethact=3Com 3c920c#0
ethaddr=00:09:D2:11:01:15
video_activate=agp
menuboot_cmd=boota; boota; boota
Now I'll set everything as needed, save and... hope.

EDIT3: I have fixed the settings and now the CRC error is gone, but the 0 kB FLASH and no VGA problems remain :x

The flash error is normal, mine does the same. The missing vga is either no graphics card installed, or faulty.

Yes, the memory error is no real issue: setting the variables and re-saving the environment fixed it. The error was simply due to the long time passed without power (I kept the machine off for months, without battery).
The missing vga is either no graphics card installed, or faulty.
I probably know now where the problem is: searching on Amiga forums, it turned out that somebody else had the same issue, and the problems was the megarray - or better, the way the CPU module sits on it. In fact, I had changed the fan and, it seems, I have tightened the screws that hold the module too much. I'll have to unmount and remount everything...

EDIT: confirmed: I loosened the screws a bit and the A1 is now back to life.
