PCI Reset Problems Associated with the Initial Version of the Universe Chip
4. Now try modifying the LSI0 env parameters, to be the same as those
on the MVME260x which failed:
printenv
vme3_lsi0_vmeaddr
vme3_lsi0_size
vme3_lsi0_phi
After a power-up, before the init code ran, the LSI0 values are:
800000 0 0 0
5. Do NOT run the init code, but press push-button RESET, and the
values become:
830001 f0000000 f0000000 0
6. Run the vme3 init code, and the values are set to accommodate env
parameters:
80821000 3000000 23000000 3d000000
7. Do a bye
The values before the init code runs are:
80820000 0 20000000 0
This gets the same results with the MVME360x as with the
MVME260x, and the difference seen earlier is related to the values
of the LSI0 slave at the time the PCI reset occurred.
