@pokey there is a compatibility list in the wiki. But I don’t want to tell you to buy a new card and you are gonna blame me if the new one doesn’t work either. There are software tools to test sd cards. And you should more or less have an idea looking at the sd card brand. Ultra high speed sd card won’t be used at full potential in a rpi though. About 20-25 MB/s is the limit afaik.
Yeah, in this case it's wired. I did some more playing with things and found out that unplugging the usb and plugging it back in crashes ES. If I do it slowly, its ok. I'm pretty sure all of this is somehow related to the kernel. Not sure what kernel reto pi uses or recalbox for that matter but I only recalbox does these things. I could maybe grab some dmesg logs on this.
Can you post the output of your /var/log/messages Also the logs from the web interface Ssh to your recalbox cd /var/log cat messages Try assigning a fixed ip from your router to your recalbox <ul class="inline-list" style="box-sizing: inherit; margin: 0px auto 1.21429rem; padding: 0px; font-size: 14px; font-family: 'Lucida Grande', Helvetica, Arial, sans-serif; line-height: 1.6; list-style: none; overflow: hidden; color: #222222;"> <li style="box-sizing: inherit; margin: 0px 0px 0px 1.57143rem; padding: 0px; display: block; float: left; list-style: none;">
