Hello Weidong,
Thank you. We're using eMMC 5.0. I believe we have a mismatch between our hardware and the reference binaries I loaded for initial evaluation. The mx7d lpddr2 image down in Profiles/Linux/OS Firmware/firmware restricts itself to using SDHC1 for MMC control. Our design follows the i.MX7D SABRE SD model and uses SDHC3. Of note, the only place I was able to find the config and board files for the reference images was in Toradex's repository. Which NXP/Freescale repositories contain this code?
This morning I built an updated mx7dsabresd u-boot image with lpddr2 timing in place (imximage.cfg) using the u-boot-fslc git repository. MfgTool absolutely refuses to open the module (first get "unable to open, error 2 " followed by ucl error 4). Went back to the "Manufacturing Tool V2 (MFGTool2) Linux or Android Firmware Development Guide" document. It refers to another document, "BSP User Guide, cahpter Build Manufacturing Firmware", which I have not been able to locate.
Where can one find a working example of MfgTool-compatible u-boot build? Ideally for me would be a working mx7sdabresd u-boot build.
Thank you, Joe
