Hi,

We would need to use UART2 in final stages of A-T-F. (UART0 and UART3 works fine)

We seem to be able to initialize and direct prints but nothing is transmitted at UART2 TX.

Have anybody successfully used UART2 for log prints ?

I've never tried to use UART2 but I found this which might be remotely relevant:

https://github.com/96boards/l-loader/commit/5f9a3a00ab1eeb4be021cda4241d8ad09a675f77

This commit claims that it will initialize UART3. I have no idea why this would belong to l-loader and not to ARM TF and/or UEFI but anyway, I thought maybe something similar is needed for UART2?

HTH,

Jerome

Thanks,

Stefan
