RE: ICON issue
And another note here, this is a side effect of the better files system underneath (the thing necessitating a format of the flash between last release and this one). Its tuned better for the flash chips, but apparently is a bit more aggressive with the optimizations to avoid writing as much.
Can you please report back if simply doing an on-off cycle resolves your problem? TW Although I work for HP, the views and opinions I post here are my own. |

RE: ICON issue
Thank you Cyrille (edit : and thank you Tim).
I've just tried : - remove all programs - reset - load test01 to test05 programs - turn off the calculator - turn the calculator back on - reset to clear the RAM - press Shift+Mem (and wait) - press Shift+Program => and I'm sorry but same problem : test02 to test05 programs get destroyed So either I didn't process exactly like you, either you were lucky. |

RE: ICON issue
What about turning the calc off prior to any reset? So remove all programs and turn off first. Then reset and load new programs.

RE: ICON issue
Hello,
Well, it definitely looks like I need to investiage further... However, as was pointed earlier, ICON is definitely not the right tool for the job here... I would sugest using .jpeg files, it will be way more memory efficient and a much better fit for the system... I assume that B&W jpeg would be the best from a memory standoint, but I might be wrong, PNG might be better.. you will have to investigate... However, I wanted to point out that there is still a 2MB limit on app sizes. We might want to change this in the future. but 2MB of jpeg b&w can correspond to a lot of pages!

RE: ICON issue
Maybe I should open a new topic ?
I've got a huge problem now. I was going on testing things with the latest firmware today. So, I was transferring the same "test01.hpprgm" file shared some posts ago. As soon as the tranfer did complete (so when the parsing starts?), this time my HP Prime turned off and I've been totally unable to turn it back on since then. It looks completely dead... I've tried removing the battery, using another battery, connecting the USB, holding the boot key combos (symb and F+C+O)... Whatever I do, the screen remains off. Did the random corruption this time affect some vital part of the NAND chip ? Thanks. |

RE: ICON issue
For information, I've managed to get a tiny little reaction from the calculator.
If I remove the battery, then when I connect the USB the screen turns on in white for less than a second, doesn't display anything, and then immediately turns back off. From then, no other reaction by trying everyting already mentionned in the previous post. Is there still anything than I can do for this calculator ? Thank you very much. |

I thought I had bricked my calculator during the upgrade when it crashed 50% through. Nothing seemed to get it back to life and I believe I tried all combinations I knew of and had read about at the forum. In the end by using the reset button through the hole at the back in combination with only the "Symb" button I got it into the "ready to update state". I had to try several times, holding the reset button for ten seconds etc. before it restarted. You may have tried this as well, but just in case... Cheers, Terje |

RE: ICON issue
Hi Tim and thank you for your reply.
I had already tried this in both previous posts. Here is what I do : - hold the reset button - hold the Symb key - release the reset button The calculator doesn't turn on. I've tried with and without the battery, and with and without the USB connected. No difference. |

RE: ICON issue
So again, what can I do ?
I've never had a bricked calculator, I don't know who to contact. If you don't understand at all what happened, maybe you'd like the calculator to be returned in a special way, in order to be able to check the NAND chip content, instead of it being immediately reflashed or destroyed depending upon your process. That's why I'm asking here first. Thanks for reading. |

RE: ICON issue
Thank you very much for your reply.
Here is a more comprehensive description. Do you remember that when sending apps over 2MB with the previous 8151 firmware, the calculator was going crazy and triggering lots of menus or dialog boxes that I sometimes didn't know of ? http://www.hpmuseum.org/forum/archive/in...832-2.html (last post) As if the rejected data over 2MB was directly written to the key buffer, or feeded to the CPU... In this context the latest firmware doesn't seem to behave like this anymore, and just shows a memory error message, but it might be related to something below. Before the last problem happened, I've experienced various strange behaviours last week with the latest firmware, when sending relatively small programs similar to the 'test01' shared some posts ago (so much less than 2MB). When a program transfer did complete, the calculator would either : - behave as expected (most of the times) - freeze - corrupt some programs like already described - immediately turn off (but I could still turn it back on) - start triggering random dialog boxes like above (but much fewer) - immediately turn off, and being harder to turn back on (*) - and on the last try with the 'test01' file which worked many times before that, turn off forever apparently (*) This only time, when I turned the calculator back on, it showed me a blank screen and seemed frozen. I triggered the reset, it then showed me a blank screen with a message like "Clearing memory" or something like this, and then did run the firmware properly but with all data lost. About the context, which might be important. I was putting the calculator either on the about screen, either on the applications screen. On the very last try, I was simultaneously sending the 'test01' program file to two calculators. I now can't see anything else that I could tell you about this problem context. Does this at least help you better understanding what could have happened ? Thanks. |

On the Android one cannot even see a folder for the calculator. Alternatively, how can a .png be turned into an ICON? I thought i read somewhere that the formats were similar, but when I downloaded a .png and renamed it as .txt, it was not an ASCII file: it was full of unprintable binary codes that I am sure wouldnt work well in an ICON.

RE: ICON issue
Hello,
I would recomand not turning a png into an ICON. a png is a file that takes little to no memory in the calculator. an ICON takes a LOT of ram :-( and can not be offloaded... Cyrille Although I work for the HP calculator group, the views and opinions I post here are my own. I do not speak for HP. |

And on the Android at least, I hope the RAM constraint might be less of an issue. Unfortunately, when I tried to convert a PNG to an ICON, I discovered that my PNG file seems to be a binary file, not readable hex - I have not tried it yet, but am sure it will not cut and paste into an ICON.

RE: ICON issue
Sorry for off topic, but it would be nice to know if user accessible folder or something in that regard is on to do list for android device or if android emulator is in its final state. :-(

RE: ICON issue
As long as we cannot send HP applications as zip files or as 1 single file, I don't think ICON should be removed. Sending applications then getting them to work properly without having to reboot your calc 3 times or so is a major PITA compared to just sending 1 .hpprgm file.
Let's get application transfer 100% functional before starting removing features that currently works. -Dream of Omnimaga https://dreamofomnimaga.page |
