Hi, Ive got a bpi r2 and I’m trying to follow the instructions to configure it to boot from the emmc, for example from here: https://www.fw-web.de/dokuwiki/doku.php?id=en:bpi-r2:uboot
When I try and selct the emmc device in u-boot I get this message:
BPI-R2> mmc list mmc@11230000: 0 mmc@11240000: 1 (SD) BPI-R2> mmc dev 0 Card did not respond to voltage select! BPI-R2> mmc partconf 0 Card did not respond to voltage select!
After that runnign mmcinfo also says ‘Card did not respond to voltage select!’ so its selected the device.
I’ve tried with the 4.14 kernel from FrankW, and just compiled the kernel 5.4.46-bpi-r2-main.
u-boot version is: BPI-R2> version U-Boot 2019.07-bpi-r2-sata_new-00035-g915f1ef772 (Jul 30 2019 - 10:50:24 +0200)
arm-linux-gnueabihf-gcc (Ubuntu/Linaro 7.4.0-1ubuntu1~18.04.1) 7.4.0 GNU ld (GNU Binutils for Ubuntu) 2.30
I feel I’m mising something, anyone have any ideas where I’m going wrong?
