| 13:26.34 | yangvnc | I am wondering if there is a way to reflash the linux firware multiple times, and if there is a risk to damage the A780 phone, if you break installation procedure somehow? |
| 14:17.47 | *** join/#openezx dion (n=dion@inhex.net) |
| 14:32.13 | ao2 | yangvnc, do you mean a _full_ flash. That may be risky. On the other hand if you don't touch the bootloader when flashing then you can always restore your phone as long as you have a charged battery. |
| 14:37.25 | yangvnc | not a full flash, can be partial |
| 14:37.37 | yangvnc | so actually with partial flash i get a dual boot phone |
| 14:37.57 | yangvnc | Origiral motorola OS and linux |
| 14:41.00 | yangvnc | I am refering to this manual http://wiki.openezx.org/Getting_Started_A780 |
| 14:52.33 | ao2 | well, this very one manual is about partitioning the _external_ flash memory and booting openezx kernel via USB. |
| 14:53.01 | ao2 | so if you want to start with this, you won't need to touch your internal flash at all |
| 14:55.00 | ao2 | after that you may want to put a second stage boot loader on internal flash, so to boot the kernel (original of not) from the external memory. We used to use blob2 for that, but now there is gen-blob. I'll write a birf document about how to use gen-blob, when I start using it. |

| 16:13.15 | WyrM | ao2, about dropping MTD_ALTERNATE, yes, I agree with you. :) |
| 16:14.08 | WyrM | now we just have to fix the remaning issues with the mmc card and the 2.4 kernel. |
| 16:30.16 | CIA-26 | OpenEZX: wyrm * r2266 /trunk/src/blob/gen-blob/src/blob/ (boot_modes.c mmc.c): |
| 16:30.16 | CIA-26 | OpenEZX: use the speed reported by the card instead of hardcoding it. |
| 16:30.16 | CIA-26 | OpenEZX: be more cautious when turning mmc off |
| 16:36.08 | yangvnc | ao2: external flash as External SD card? |
| 16:36.55 | yangvnc | ao2: on the top i have found a tiny CARD transflash 256MB |
| 16:37.37 | yangvnc | how much space does the linux boot take? |
| 16:38.04 | WyrM | yangvnc: on the internal flash? or on the card? |
| 16:38.09 | yangvnc | on the card |
| 16:38.16 | WyrM | 1.5 mb. |
| 16:38.20 | yangvnc | :) |
| 16:38.28 | yangvnc | good |
| 16:38.48 | yangvnc | Are there also mirrors where I can update the software for this phone? |
| 16:39.15 | WyrM | update the motorola software? |
| 16:39.23 | yangvnc | no this openezx |
| 16:39.58 | WyrM | you can compile yourself with the code on svn.openezx.org |
| 16:40.23 | yangvnc | ok |
| 16:40.25 | WyrM | or you can browse people.openezx.org and find some pre-compiled kernels.. |
| 16:40.52 | WyrM | but you will also need an rootfs on the card to use OpenEZX. |
| 16:41.05 | WyrM | we are using the ones from the Angstrom distribution. |
| 16:41.20 | WyrM | the rootfs will use at least ~40 mb. |
| 16:41.22 | yangvnc | I am installing according to this manual - http://wiki.openezx.org/Getting_Started_A780 |
| 16:43.02 | WyrM | yangvnc: good. |
| 16:43.50 | WyrM | download a rootfs image from angstrom (there is a link on this wiki page) and follow the howto, and you will have linux 2.6 running easily. :) |
| 16:44.50 | WyrM | but note that this howto is for sending kernels via boot_usb, so it is safe, but you will need a nearby computer to start it. |

| 17:24.13 | ao2 | WyrM, my A780 is now charging, when it's done I will start the blob2-undo and then install gen-blob, writing a little tutorial about the whole process, I don't think there's some doc about gen-blob, isn't there? |
| 17:25.29 | ao2 | given the simplified aaproach now I can see clearly the openezx-ifier based on initrd you talked about once |
| 17:35.58 | flyhorse|linux | can usb charge now during runing the kernel-ezx ? |
| 17:37.45 | WyrM | flyhorse|linux: when running from flash (BP in normal mode) it is possible. |
| 17:38.13 | WyrM | ao2: yes, simple and fast! :) flashing gen-blob to the kernel partition takes just some seconds. |
| 17:38.38 | WyrM | ao2: there is no documentation other than the README file, but it is very incomplete. |
| 17:44.48 | flyhorse|linux | i mean using usb_boot for boot |
| 17:52.24 | WyrM | flyhorse|linux: no, it is not possible on a780, the AP has no access to the PCAP registers for battery. |
| 17:52.43 | flyhorse|linux | o .. |
| 17:52.52 | WyrM | flyhorse|linux: on a1200 and other gen2 phones, it may be possible, but i never tried it. |
| 17:52.52 | flyhorse|linux | and what about e6 ? |

| 20:44.47 | ao2 | WyrM, to undo blob2 changes it is enough to merge these two pairs of flash partitions, right: |
| 20:44.50 | ao2 | 00020000-0003ffff13107299Second blob (added) |
| 20:44.50 | ao2 | 00040000-0011ffff91750498Motorola Kernel (moved) |
| 20:44.52 | ao2 | and |
| 20:45.08 | ao2 | 00120000-0187ffff2451046433rootfs (resized) |
| 20:45.08 | ao2 | 01880000-019fffff157286497OpenEZX Kernel (added) |
| 20:45.46 | ao2 | so Motorola kernel one will be again 00020000-0011ffff |
| 20:45.58 | ao2 | and rootfs 00120000-019fffff |
| 20:47.59 | WyrM | there is no need to merge the partitions, all you have to do is re-flash the original rootfs (without the resize). |
| 20:48.18 | WyrM | this, using a kernel with the original mapping, not the alternate mapping. |
| 20:49.25 | WyrM | with the original mapping, those 2 are already merged. |
| 20:50.53 | WyrM | and, you flash gen-blob to the kernel partition (original mapping) |
| 20:51.18 | ao2 | ok, that's even faster than I thought |
| 20:52.19 | WyrM | ao2: and reflashing the rootfs is optional, you probably deleted only useless stuff when you shrink the rootfs before. :) |
| 20:54.43 | ao2 | yes, that's true, anyway I'll write about how to save the 2.4 from flash when in a blob2 setup using the ALTERNATE map, so to have a fully legal way to do it. |
| 20:56.08 | ao2 | even if people that used blob2 should be able enough to get a clue by themselves |
| 20:59.43 | WyrM | ao2: for a blob2->gen-blob tutorial, the ideal is to use only mtd_alternate mapping. |
| 21:00.41 | WyrM | on a single boot, you can flash gen-blob (to alternate blob2 partition) and read the 2.4 kernel (from alternate moto kernel partition). |
| 21:08.00 | ao2 | yes, avoiding unuseless writes to flash is better for now. Even if I still consider ugly (but harmless, I know) to have trailing residual data written somewhere on flash :). Let's be pragmatic, tho. |
