Hello, I'm looking for some help fixing a possible issue on AR9331 platforms covered by the AR71xx target. In uBoot we're getting nothing but framing errors over serial. Once Linux initializes the port. everything works fine. Digging in the code, I've been able to find that the Linux driver for the UART:
- Enables the UART - Pokes a Startup code to a register - Sets Bit rate - Set Parity, length and stop bits. All I can find in the uBoot code is it setting the bit rate. Am I missing where the driver is doing the things the Linux driver does? The data sheet seems to indicate that the UART Enable and Startup deals with pin multiplexing, defaults, and clock selection. I'm wondering if that's causing our issues. We're using 15200/n/8/1 for Linux and uBoot. I'm using a vendor provided version of uBoot. Thanks, Mike _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
