Manfred & Albert, The patch did work.
Thanks, James P.S. Unfortunately my MUA is OWA, and I cannot change the line length myself. ________________________________________ From: Manfred Huber [man.hu...@arcor.de] Sent: Tuesday, April 02, 2013 1:25 AM To: James Chandler Cc: u-boot@lists.denx.de; Scott Wood; Albert ARIBAUD; Javier Martinez Canillas Subject: Re: [U-Boot] AM3517_EVM, MLO not booting Hello James, you found the same bug in the ROM code of some OMAP3 devices as I did. Look at the Patch 'Flush UART3 xmit on enable if TEMT is broken'. Try the Patch and let us know if it works.
