Hi!
What is the status of the ordb2a-ep4ce22 SDHC support? Booting from the SD-Card using orpmon does not work at all. Is there any support for U-Boot? (oprmon sucks anyway...) A Linux-Driver for the SDHC would be also nice to have. Thanks, //richard |

Hi Richard
SDHC controller that is implemented on ordb2 board (sdcard_mass_storage_controller) is supported by eCos RTOS. It is possible to use it in eCos applications as well as in RedBoot - eCos based bootloader. Our blog note describes how to add the driver to eCos build: http://antmicro.se/Blog/2012/05/sd-controller-driver-for-openrisc-ecos/ Best regards Piotr |

So, using RedBoot I can boot a Linux kernel from the SD-Card? Sounds good! Thanks, //richard |
