Honestly, you can get a replacement R444 for like a penny (or even 10 for a penny)... TI doesn't even "fully" support this configuration yet.. http://processors.wiki.ti.com/index.php/Linux_Core_U-Boot_User%27s_Guide#Using_SD.2C_eMMC_or_USB_storage http://processors.wiki.ti.com/index.php/Linux_Core_U-Boot_User%27s_Guide#Using_SATA > > If I made the hardware modifications correctly this leaves me with the issue > of a board that does not boot and there is no way of going back to soldering > the original resistor (destroyed during removal).

This may be my only option. When v2017.11-rc1 get's tagged, i will re-enable it, so we will see. One of the issues we ran into with v2017.01 when this option was enabled, some board/esata combations would "lock-up" on poweron.. Thus the image was broken on more boards then users who used the esata... > Any other advice would be greatly appreciated. Thanks again for your > intruction and response. While the "boot" room, supports loading files from the sata drive at bootup. It's not fully enabled/tested in U-Boot yet.. There's also a bug here (LCPD-5517): http://processors.wiki.ti.com/index.php/Processor_SDK_Linux_U-Boot_Release_Notes LCPD-5517 P3-Medium Board fails to load bootloader sometimes when eSATA is connected Connectivity UBOOT AM572x Regards, -- Robert Nelson https://rcn-ee.com/ -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
