Thank you! I found your response helpful. I tested *bbxm-debian-9.9-lxqt-xm-armhf-2019-04-28-4gb.img.xz* image with my existing card and it booted reliably. I tested both cold boot and restart multiple times. I did not even see the mmc issue come up once with that image.
I'm still considering buying a better SD card. I found this thread discussing the issue from 2015 https://github.com/RobertCNelson/armv7-multiplatform/issues/25 . As far as I understand, the issue is not read/write speed, but rather SD-card's boot time which is not typically specified for SD-cards and might not correlate with the card's price range - that makes an informed choice more difficult. I think I'll first try *Strontium Nitro 16 GB Class 10* card. Do you have any recommendations with regard to SD-card products or brands that have worked for you in the past? *** As a side note, I successfully moved the image to SD-card using *dd*. However, I noticed the image build directory had a **.bmap* file so out of curiosity I tried using *bmaptool* to flash the card, however it failed. Was I doing it right?
