ip2 (cﬁg_regtest) - Check Conﬁguration Registers

Basic write/read test for the conﬁguration registers. The registers tested are limited to the

following:

EV_PGBRDEN Write gatherer destination

EV_PROC_DATARATE Write gatherer control

EV_WGRETRY_TOUT Interrupts 0 - 63

EV_CACHE_SZ Interrupts 64 - 127

EV_CMPREGO - 3 Timer comparator registers

Note: The timer comparator registers are checked via the read-only RTC compare

Possible error:

0103002: Configuration Register %s R/W error : Wrote 0x%llx Read 0x%llx

ip3 (bustags_reg) - Check Bus Tags

This test calculates the size of bus tag space based on the size of the secondary cache. Then

it performs basic write/read test on the bus tags.

Possible error:

0103003: Bus tag addr 0x%x R/W error : Wrote 0x%x Read 0x%x

ip4 (counter) - Check R4K Count/compare Test

This test performs a basic write/read test on the R4K compare register ﬁrst. Then it

generates an interrupt using the R4K count and compare registers.

Possible errors:

0106001: Compare register data error : Expected 0x%x Got 0x%x

0106002: Incorrect contents in count register : Expected 0x%x Got 0x%x

0106003: Phantom count/compare interrupt received

0106004: No count/compare interrupt received : Count 0x%x Compare 0x%x
