J721S2XSOMXEVM: Mapping of Padconfig to Example Source Code in PDK

Tool/software:

Hi,

I think I am referencing the wrong Package Padconfig or PDK Source Code refers something else.

I am trying to map the Pads/Pins in ALZ Package from TDA4VE TDA4AL TDA4VL JacintoTm Processors, Silicon Revision 1.0 datasheet (Rev. B)
According to that, PADCONFIG_11 is 0x0011C02C, but in the PDK GPIO Example(test/led_blink.c) the config looks like this,

#if defined (SOC_J7200)
#define PADCONFIG (0x0011C000) /* PADCONFIG_0 */
#elif defined (SOC_J721S2) || defined (SOC_J784S4) || defined (SOC_J742S2)
#define PADCONFIG (0x0011C0C8) /* PADCONFIG_11*/
#endif

So, I would like to check, what is the correct package and correct mapping.

I am using,

  • J721S2 SOM (PROC118E3), J7X CPB(PROC079A)
  • RTOS SDK 11.0.0.06
  • PDK 11.0.0.21

The reason for my question is, Pinmux config in pdk doesn't match the ALZ Package addresses, which is probably why my I2C or SPI devices don't seem to work.

Thanks.

Best,
Moses
