6 OnRISC Hardware API

Figure 4: Watchdog Timer Support

6.9. Read Hardware Parameters like MAC Address, Serial Number etc.

6.9.1. KS8695 based Devices

Such parameters as MAC addresses, serial number etc. are stored in ﬂash and can be accessed via

special structure:

1 struct _param_hw // v1 .0

2 {

3 byte pad [ 1 ] ;

4 u sh o rt szram ; // d i r e c t in MB

5 u sh o rt s z f l a s h 2 ;

6 u sh o rt s z f l a s h 1 ; // d i r e c t in MB

7 byte mac2 [ 6 ] ;

8 byte mac1 [ 6 ] ;

9 u sh o rt b i o s i d ;

10 char prdd ate [ 1 1 ] ; // as a s t r i n g i e . " 0 1 . 0 1.2 0 0 6 "

11 ulon g s e r i a l n r ;

12 ulon g hwrev ;

13 ulon g magic ;

14 } __attribute__ ( ( packed ) ) ;

See hwtest/hwtest.c->param_read_hw_params() routine on how to read the parameters from

ﬂash.

6.9.2. OMAP3 based Devices

1 typedef struct _BSP_VS_HWPARAM // v1 . 0

2 {

3 ULONG Magic ;

4 ULONG HwRev ;

5 ULONG SerialNumber ;

6 CHAR PrdDate [ 1 1 ] ; // as a s t r i n g i e . " 0 1 . 0 1.2 0 0 6 "

7 USHORT SystemId ;

8 BYTE MAC1 [ 6 ] ;

9 BYTE MAC2 [ 6 ] ;

10 BYTE MAC3 [ 6 ] ;

11 } BSP_VS_HWPARAM;

Use onrisctool.py without parameter and you’ll get a list of all parameters stored in EEPROM.
