[RDV4] Received latest PM3 RDV4.01 however uC seems not right

I received the latest version of PM3 RDV4.01 (from lab401) however, when I checked the hardware, the CPU/uC of this pm3 is "AT91SAM7S512 Rev A".  I think this CPU/uC is for old version of PM3.

Is it supposed to be "SAM7S512" for pm3 RDV4? The packaging says definitely RDV4.

Anyone else has checked their RDV4? Do you have the same CPU/uC "AT91SAM7S512 Rev A"?


The details of the hardware are below:

[ Hardware ]
  --= uC: AT91SAM7S512 Rev A
  --= Embedded Processor: ARM7TDMI
  --= Nonvolatile Program Memory Size: 512K bytes, Used: 237349 bytes (45%) Free: 286939 bytes (55%)
  --= Second Nonvolatile Program Memory Size: None
  --= Internal SRAM Size: 64K bytes
  --= Architecture Identifier: AT91SAM7Sxx Series
  --= Nonvolatile Program Memory Type: Embedded Flash Memory

... You are talking about the same MCU... 

AT91 SAM7S512 Rev A  == SAM7S512


For RDV4 we have used two different hw revisions of the MCU. Read the Atmel's errata for that model if you interested in their changes.
Not that it changes anything for your device.

MCU revisions:
AT91SAM7S512 Rev A
AT91SAM7S512 Rev B

I suggest you edit your first post and add the suffix [solved] to your title
