Dear Sir,
I am testing RTEMS kernel example and rtems-libbsd USB example on Beaglebone Black board. When I test RTEMS kernel ticker example, there was not any problem. But, when I test rtems-libbsd/usb, there is below error. If anyone test USB on TI beagle board successfully, please advise me. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ U-Boot 2018.01-g57f10f0441 (Apr 06 2019 - 04:45:02 +0000) CPU : AM335X-GP rev 2.1 Model: TI AM335x BeagleBone Black DRAM: 512 MiB NAND: 0 MiB MMC: OMAP SD/MMC: 0, OMAP SD/MMC: 1 *** Warning - bad CRC, using default environment <ethaddr> not set.
