Part Number: TMS570LC4357
Other Parts Discussed in Thread: HALCOGEN, , TMS570LS3137

I checked the EMAC registers between LS3137 and LC4357 , I found the address of them is the same.Why can't the same code work?

Should I check the system setting?Others system codes are generated from HalCoGen.

Hello,
EMAC Driver for TMS570LC4357 is not same as the one for TMS570LS3137. Some of differences comes with shared and not shared ram. See errata document for some other problems while trying to use other driver (DEVICE#54).

Best regards,
Miro

Hello,
You can not use EMAC driver generated for TMS570LS3137 with TMS570LC4357.
For example, In errata document you could find more on DEVICE#54 issue.
