Regarding the SoftConfig settings for SC598 Rev D

Hi,

I was trying out the LED blink example for my EV_SC598_SOM and its EZKIT, and it seems that the SoftConfig setting didn't work (as it gives me the adi_twi_write failed for all of its SoftConfig settings) but the GPIO call for the EZKIT lights up the LED. I tried to look at the softconfig settings, and it seems that the hardware address is 0x34u, instead of the 0x21u from the SC598_SOM manual. Since the SoftConfig settings provided from the example is REV E,while my current board is "REV D Z", I wonder if there are changes in the TWI address for this SoftConfig switch?
>> Yes, your understanding is correct. If you want to use the "EV-SC59x_EZ-KIT-Rel4.0.0" BSP package, please modify the SoftConfig switch to set "HardwareAddress" to 0x20u instead of 0x34u.

Since you're using the EV_SC598_SOM "REV D Z" board, we also suggest using the previous release BSP package, "EV-SC59x_EZ-KIT-Rel3.2.0," as it supports the REV D board. You can download the BSP for ADSP-SC59x/2159x rev 3.2.0 using the following link:
https://download.analog.com/tools/EZBoards/EV-SC59x/Releases/Release_3.2.0/ADI_EV-SC59x_EZ-KIT-Rel3.2.0.exe

After installation, you can find the LED blink example from the below mentioned installation path. Please make use of this example.
path: \Analog Devices\EV-SC59x_EZ-KIT-Rel3.2.0\EV-SC59x_EZ-KIT\Examples\services\gpio

I don't quite understand the manual pdf on why there are two hardware address, 0x21u and 0x22u for the SC598_SOM board. Isn't 0x22u the hardware address for the EVKIT softconfig? Could you please clarify?
>> "HardwareAddress" need to be modified as "0x20u". Thank you for pointing this out. We will check and update the documentation in the future release.
