My customer is using the Colibri T30 module for their production solution (u-boot 2016.11 from latest Toradex Linux BSP doesn't help :-) ) To sum up: ---------- 1. I think that the WDT driver is required for the Tegra 30 to be usable in any professional use case based on u-boot. 2. It would be best to modify the colibri_t30_defconfig to add support for WDT. 3. If point 2 is not possible (please share the rationale for it) - then I can ask my customer if I can share defconfig for their product. > Francesco >=20 --=20 Best regards, Lukasz Majewski -- Nabla Software Engineering GmbH HRB 40522 Augsburg Phone: +49 821 45592596 E-Mail: office@nabladev.com Geschftsfhrer : Stefano Babic
