Unfortunately this still doesn't work as it should. I've been doing more tests and I found out MMC/SD *does* work, but with a ridiculously low throughput (~20KB/s) which is enough to trigger WDT loading uImage. Adding explicit "max-frequency = <48000000>;" to .dts *seems* to cure speed problem, but makes transfer unreliable: relatively small files (<200k) usually work fine, but larger files invariably exit with error: Error reading cluster ** Unable to read file uboot-ram.bin ** after which mmc subsystem is unusable (till next reset). @Stefan: do MMC/SD work right on LinkIt/Gardena ? apparently neither define mmc section in .dts Enabling Debugging I have the following (opaque to me) output: ============================= U-Boot 2020.01-00646-gdec191f2a0-dirty (Jan 27 2020 - 12:23:17 +0100) CPU:

I fear I'll have to wait Weijie input on this. I'll keep this as is now, till further notice. ANY input very welcome. Regards Mauro
I just trimmed too much. This is also the cause of MMC/SD misbehavior (missing interrupt). I will send another patch *after* some serious testing.

Hi Mauro, (This is my personal mail account.) Please don't copy and paste from my out-of-date patches. You are copying code from v1 https://patchwork.ozlabs.org/patch/1154190/ which has already been replaced by v3 https://patchwork.ozlabs.org/patch/1167073/ SInce v3 is the mainline version, you should drop all modifications from v1 and rebase your patch based on v3. Basically you should drop all modifications of arch/mips/dts/mt7628a.dtsi. I'll give comments on your next patch.

Small patch series to add support for VoCore/VoCore2 board. VoCore is open hardware and runs OpenWrt/LEDE. It has WIFI, USB, UART, 20+ GPIOs but is only one inch square. It will help you to make a smart house, study embedded system or even make the tiniest router in the world. Details about this SoM can be found at "https://vocore.io/v2.html".
