Hello,
I am trying to have the vitesse vsc7385 phy switch working with a mpc8548 cpu on my system. Currently I am using the MPC8349 mITX box as my reference. And my question is where to obtain the official image for the vsc7385.
The U-Boot I have in my mITX box is U-Boot 1.1.3. It looks like that this U-Boot dose not bring up the vsc7385 during the eTsec initialization, instead, the U-Boot bootcmd run a script to fetch a 4k image from of the flash memory address to init the vsc7385. By my understanding, correct me if I am wrong, this 4k image must contains a payload for the vsc7385 internal CPU (8051) with a wrapper for the mpc8349 to put the payload through local bus to the internal memory of the 8051.
I also looked at the latest U-Boot for the mITX box. Looks like that the latest U-Boot load the vsc7385 image to the internal memory of the 8051 and let 8051 run it in the misc_init_r() function, before the eTsec initialization. The MPC8349ITX.h defined CONFIG_TSEC2 for the vsc7385 and the tsec initialization will trade this vsc7385 as a generic phy. Therefore I suppose here the image for the vsc7385 is different from the image I have in my mITX box since no wrapper is needed for loading the image.
So where I suppose to get the official image for the phy switch?
Thanks
