Hi , we are developing a product using nano production SOM, we are trying to implement the external sd card port into use for emmc. Thus we require this sdio line to maintain 1v8 , we have confirmed that there is no issue while booting, but after booting we observed voltage changing up to 3v3 , thus we would like to know a way to keep it at 1v8 so that our emmc would work properly, we have seen some forum post , where some people where able to make nano SOM operate with 2 emmc’s. So could you please guide us to keep the sd card sdio line fixed at 1v8 without changing to 3v3. thank you.
