Occasional Contributortriple speed ethernet (TSE) driver for ARM
Hello,
I need to implement TSE driver for arm in a baremetal project.
I am not sure how to start doing it.
Is it best to start from u-boot driver:
https://github.com/lentinj/u-boot/blob/master/drivers/net/altera_tse.c
I assume it should be function with ARM, right ?
Or is it better to start with altera_tse driver as generated for NIOS ? should it be also functional in ARM ?
Thank you,
ranran

Hi Ranran, It's really up to you how you want to start your project development. However, I do find below reference design that maybe useful to you. https://rocketboards.org/foswiki/Projects/AlteraSoCTripleSpeedEthernetDesignExample Thanks. Regards, dlim- rshal2
Hello dlim,
We have a reference which already works with NIOS.
Is it possible to build the altera tse driver as-is (from nios) in arm ?
Do you think it should work with its sgdma ?
Or do you expect that we should make modifications in this driver and firmware ?
I ask again, becuase I think that starting from altera driver - if possible - can make life easier.
What do you think ? Another alternative is to use maybe u-boot driver for tse.
Any tips and suggestion is appreciated.

- Deshi_IntelHi Ranran, So the questions will be back to your application design requirement. Is it fine to use just NIOS II processor or do you need more powerful ARM processor ? In previous reply, I also shared with you one reference design link that use HPS ARM processor to interact with HPS-FPGA bridge then to TSE IP. Isn't that what you need ? Thanks. Regards, dlim

Dlim,
That's really very helpful.
You fully answered my questions for now.
Thank you very much,
