Sure I do. I can arrange temporary remote access to my unit's serial console and USBnet ssh,
so you'll be able to check whatever you need. Let me know if interested. |

Thank you for all the work you guys/gals have done. I just picked up my KPW (upgrade from sony 650). While I liked the simplicity of the sony UI, the KPW screen and light overcame amazon's poor UI for the kindle but I had to integrate my calibre collections! I turned on airplane mode and went through the steps provided and now have kindle collections working on my jailbroken 5.3 PW. I appreciate your efforts and help in this!

I am old and work slow, so it may be awhile before I need to roam around in the 5.3 system. Will see if I can get it running under emulation first. But if you've clicked through to my own web site (I'm just a visitor here) you will see that I am very much opposed to locked consumer devices. Link is my "homepage link" in the info box on the left. Note: Most of my web site is hidden from the public eye, only visible to members logged in. Anyone that wants to register will need a "passcode" for the registration form - just PM me here for that. |

Could you please check if issuing "setenv bootargs parameters" command before booting would change kernel cmdline? (environment variables in u-boot should last only until next reboot). Also, could you check what "bist fastboot" does? (if it'll appear to boot fastboot, then don't forget to connect usb cable in order to check if it works ) Those two things seems to be most interesting for me.
And now, thing not necessarily for you, but for everyone who can help - could someone prepare instructions for connecting PW with serial cable for someone who never did anything like that before? It's a disadvantage of owning only open devices - you can't learn how to obtain access to them, cause you have it since beginning |

The connection points are indexed in the prefix index under Hardware / Serial Port / Kindle Paperwhite.
To save you the clicks: https://www.mobileread.com/forums/sho...d.php?t=195769 It is a LV (low voltage) serial connection (1.8 volt). Communications parameters are: 115200, 8n1 I recommend the LV serial to USB adapter cable documented in the links of this thread starter post: https://www.mobileread.com/forums/sho...d.php?t=170566 |

has no effect. At the same time the 'saveenv' command is not implemented, i.e. there's no way to retain the setting untit next boot. AFAIU, bist stands for "BuiltInSystemTest". I'd prefer to avoid running that. Looks like that detailed reviewing the 5.3.0 u-boot source code could be most efficient at this stage. I tried to formally build the u-boot from supplied source tree, but quickly learned that a key file (boardid.h) is missing. Had to recreate this file from various pieces from various sources. Now this file is still incomplete and only partially correct, but the u-boot binary can be formally built. Quote:
Below is the PW specific, as I see it:

boardid.h file can be found This file is missing either from the u-boot or kernel subtree in Amazon's 5.3.0 archive. The boardid.h found in the kernel subtree of 5.1 archive (referred by your link) is incomplete and doesn't contain the latest board type definitions. The boardid.h found in the kernel subtree of 5.2 archive has definitions for KPW, but doesn't contain definitions for ICEWINE and ICEWINE_WFO boards refered by uboot/board/imx50_yoshi/imx50_yoshi.c of v5.3.0 ... Once we are talking... my guess that the plain KPW is CELESTE_WFO_256, but is the platform YOSHI, YOSHIME, YOSHIME_3 or something else? |

ICEWINE is the codename of something after CELESTE, so you can't buy it now, I presume. So just put anything with prefix 00D for ICEWINE and 00E for ICEWINE_WFO to satisfy compiler (00D is written in /etc/upstart/functions and 00E is just distinctive from 00D, as _WFO models have distinct ID). celeste is made on yoshime3 platform. |

With executing bist fastboot you're just saving fastboot argument for second-stage ("bist") U-Boot in memory and loading that second-stage U-Boot. |

so I was even specially avoiding reading anything related to it. Quote:
But bist alone looks more interesting. It brings the version of uboot having noticeably richer command repertoire: Spoiler:
this certainly requires more thinking.. Update: I confirm that typing bist fastboot to a uboot prompt causes the PW to enter the USB Recovery mode: Spoiler:
it exits back to a bist> prompt when the USB cable gets disconnected. Last edited by h1uke; 11-15-2012 at 03:24 AM. Reason: new info |

The Kpw can be downgraded and/or de-bricked but it requires use of the serial port and some operator skill. |

That's great news, thank you! So there's a hope for poor spirits like mine who carelessly upgraded to 5.3.0 before its true evil nature was found out, thank you once again!
