As discussed in a chat, I tried SDR104 with my SDIO WiFi cards: H3: - one slot worked flawlessly - one slot could load FW but failed to read status (with SDR50: both slots work) M3-W: - both slots could not load the firmware (with SDR50: one slot works, one fails to load FW) The cards, however, were correctly identified as SDR104 and there were no tuning errors and no other SDHI related warnings. Changing TDSEL in the PFC did not change anything. The manual of the WiFi card (u-blox EMMY-W1) mentions a maximum line length of 100mm. Measuring a direct line from the SoC to the slots, I'd think we are very much on the edge of that. And given the length of the SDIO adapter, we are surely exceeding that :( Maybe we should do more tests with more boards? On the other hand, it seems the WiFi card is running out of the specs. So much for now. I'll sleep over it and try to get more data tomorrow. Regards, Wolfram
