Booting from SD card - bingo600 - 06-20-2020 I had update on the Devel channel - and Dev 53 on my PP (eMMC) , and decided to try to boot from SD. I have just downloaded the latest "Stable" from here - It says Stable 53 https://ci.ubports.com/job/rootfs/job/rootfs-pinephone-systemimage/ Unpacked , and wrote the img file to a Sandisk Ultra 32GB card w. etcher , no errors. Inserted the SD in the PP , and did a started the phone. When it booted, it asked for my "screen lock code" , and it was connected to my WiFi Now i'm in doubt if it has booted from the SD card at all, if it doesn't use the eMMC , how does it know my Screenlock code & wifi passwd ?? I somewhat expected it to boot up as "Factory reset" , or ?? My SIM card was not working, i had to go to Cellular settings and select my "provider number" 23xxxx (Telia) It was set to Auto , and 23xxx was listed below. Once i chose the 23xxx it connected to GSM , and showed Telia. When i went into update settings - , and had a look it now shows stable, so something has happened. And there was actually an update waiting, even though i just downloaded "latest" - Where's the SHA-Sum of the file !!!! The update is named Ubuntu Touch Version 3 , and i think that's the old Dev 53 , that @Luke promoted to Stable 2 days ago. I guess my question is does the OS/PP have some persistent storage where it saves Screen & WiFi pwd's ? Or does it "sneak read" from the eMMC, even if it is booted from the SD ? Right now i'm updating my PP with the Stable 3 , that update said it found OTA. More to come /Bingo Wutt !! After updating with the OTA , and reboot. It now seems to be Factory reset. The first thing i'm asked after the reboot is to set Language Yupp , i just went through a "Factory reset setup" , Lang,TZ,Screen-pwd, WiFi-pwd". Strange !!! , is this intended behaviour , or just a "Quirk" ?? I downloaded Teleport (telegram) , and gets the verification code via sms , but it wont accept it. I didn't see that issue on the eMMC install , but it could be app related. Edit: On 2'nd try & SMS , it registered , even if it still said the sms code was too long Well giving stable 3 a go today, and prob switch to Devel in the afternoon. Once again thank you for your efforts /Bingo Hmm .... Code: root@ubuntu-phablet:~# lsblk Seems like there is a partition called /android/persist - that according to lsblk is on the eMMC (if i read that correctly) RE: Booting from SD card - bingo600 - 06-20-2020 FYI tkaiser writes here (in 2016 though) https://forum.pine64.org/showthread.php?tid=681&pid=6232#pid6232 Pine64 is limited to ~22/23 MB/s sequential speed anyway (as most other Allwinner SBC) and the most important performance factor is random I/O. So take care that you choose cards that show high random I/O performance especially with small record sizes that are from one of the few manufacturers that build their retail products from both their own NAND chips and own controllers: http://forum.armbian.com/index.php/topic...rformance/ He's one of the leading forces on Armbian , and knows his SOC. This indicates to me, that a Sandisk Ultra vs Sandisk Extreme would prob have same performance in the PP. Just make sure you get an original card, the extra performance of the Extreme would prob not be utilized on the PP. Edit: The PP uses an Alwinner SOC , not a Pine64 SOC But i'd still expect a Sandisk Ultra to be able to fully utilize the SoC /Bingo |
