RTOS/AM6548: Problems initialising ICSSG ETH PHY with Board_Init

Alex Untevskiy

Part Number: AM6548

Tool/software: TI-RTOS

Hello,

I have issues initialising ETH PHY's (both CPSW and ICSSG) using the Board_Init() Function. At one point the program is waiting for a bit in PRU_ICSSG0_PR1_MDIO_V1P7_MDIO_ICSSG_USER_ACCESS_REG_j to become zero.

This never happens so the program polls forever in an infinite loop:

CPSW behaves in the same way just with a CPSW specific address.

Any advice on why this might be happening? I am not sure if im missing some configurations steps, so far I have been following the examples provided and Board_Init appears to be the first step of initialisation.

Im using:

AM65x/DRA80xM Industrial Development Kit

CCSv8

XDS560v2 STM USB Emulator

Thanks,

Alex

Alex,

Are you following the steps to run the CPSW/ICSSG example?

Hello Garrett,

yes I have been following that one and performed the Debug Setup with DMSC Firmware Load. According to the GEL output everything has been initialised successfully. Most of the code I have debugged so far worked fine aswell, the only thing that doesnt seem to work is the PHY initialisation.

Thanks,

Alex

Alex,

Is the issue still pending? The binary generated in pdk_am65xx_1_0_4\packages\ti\binary\Emac_Icssg_TestApp\bin\am65xx_idk should work as is.

Garrett,

we resolved the issue yesterday. The issue came from MMU initialisation, attrIndx wasnt set to zero after a previous definition. Therefore the memory was cached for the ICSSG and CPSW so the PHY's were not working to begin with.

Alex
