Discrepancy ot TRM spnu499b and Halcogen 03.08.00 code - CPU Reset Control Register

Jiri Janacek

Other Parts Discussed in Thread: HALCOGEN

Hello,

the technical reference manual names a register at the address FFFF FFCCh as CPURSTCR. But within the Halcogencode this register is called as MMUGCR.

I guess that a description within TRM is a bit confusing:

"The CPURSTCR register shown in Figure 2-47 and described in Table 2-61, allows the memory protection

mode to be configured. It also allows a reset to the Cortex R4 CPU to be generated."

There are no user-accessible bits related to MPU.

Best regards,

Jiri

Hello Zhaohong,

I would extend the list of discrepancies a bit more ;-) Following symbolic names are not completely different - anyway strings are not identical:

Thanks and best regards,

Hello,

the update of the register MMUGCR-> CPURSTCRin file reg_system.h is confirmed and implemented in HALCoGen: 04.00.00 - Released 20.May.2014.

But there remains the obsolete name as a part of identifiers / macros:

CONFIG_MMUGCR in system.h.

SYS_MMUGCR_CONFIGVALUE in system.h

Thanks and cheers, Jiri
