11 | Usage | ||
12 | ----- | ||
13 | |||
14 | mks5lboot --bl-inst <bootloader.ipod> [-p <pid>] [--single] | ||
15 | --bl-uninst <platform> [-p <pid>] | ||
16 | --dfuscan [--loop [<sec>]] [-p <pid>] | ||
17 | --dfusend <infile.dfu> [-p <pid>] | ||
18 | --dfureset [--loop [<sec>]] [-p <pid>] | ||
19 | --mkdfu-inst <bootloader.ipod> <outfile.dfu> [--single] | ||
20 | --mkdfu-uninst <platform> <outfile.dfu> | ||
21 | --mkdfu-raw <filename.bin> <outfile.dfu> | ||
22 | |||
23 | Commands: | ||
24 | --bl-inst Install file <bootloader.ipod> into an iPod device | ||
25 | (same as --mkdfu-inst and --dfusend). | ||
26 | --bl-uninst Remove a bootloader from an iPod device (same as | ||
27 | --mkdfu-uninst and --dfusend). | ||
28 | |||
29 | --dfuscan scan for DFU USB devices and outputs the status. | ||
30 | --dfusend send DFU image <infile.dfu> to the device. | ||
31 | --dfureset reset DFU USB device bus. | ||
32 | |||
33 | --mkdfu-inst Build a DFU image containing an installer for | ||
34 | <bootloader.ipod>, save it as <outfile.dfu>. | ||
35 | --mkdfu-uninst Build a DFU image containing an uninstaler for | ||
36 | <platform> devices, save it as <outfile.dfu>. | ||
37 | --mkdfu-raw Build a DFU image containing raw executable | ||
38 | code, save it as <outfile.dfu>. <infile.bin> | ||
39 | is the code you want to run, it is loaded at | ||
40 | address 0x2200030c and executed. | ||
41 | |||
42 | <bootloader.ipod> is the rockbox bootloader that you want to | ||
43 | install (previously scrambled with tools/scramble utility). | ||
44 | |||
45 | <platform> is the name of the platform (type of device) for | ||
46 | which the DFU uninstaller will be built. Currently supported | ||
47 | platform names are: | ||
48 | ipod6g: iPod Classic 6G | ||
49 | |||
50 | Options: | ||
51 | -p, --pid <pid> Use a specific <pid> (Product Id) USB device, | ||
52 | if this option is ommited then it uses the | ||
53 | first USB DFU device found. | ||
54 | -l, --loop <sec> Run the command every <sec> seconds, default | ||
55 | period (<sec> ommited) is 1 seconds. | ||
56 | -S, --single Be careful using this option. The bootloader | ||
57 | is installed for single boot, the original | ||
58 | Apple NOR boot is destroyed (if it exists), | ||
59 | and only Rockbox can be used. | ||
60 | |||
61 | |||
62 | Dual bootloader installation | ||
63 | ---------------------------- | ||
64 | |||
65 | Prerequisites: | ||
66 | |||
67 | - An iPod Classic 6th with Apple firmware installed and running, current | ||
68 | supported FW versions for existing models: | ||
69 | |||
70 | Classic 6th 80/160 Late 2007 (1G): 1.1.2 | ||
71 | Classic 6th 120 Late 2008 (2G): 2.0.1 | ||
72 | Classic 6th 160 Late 2009 (3G): 2.0.4 | ||
73 | Classic 6th 160 Late 2012 (4G): 2.0.5 | ||
74 | |||
75 | - If your iPod is formated using Apple partitions you must convert this | ||
76 | ipod to FAT32 format (aka a "winpod"), see http://www.rockbox.org/ | ||
77 | wiki/IpodConversionToFAT32 | ||
78 | |||
79 | - It is recommended to install the RB firmware before installing the dual | ||
80 | bootloader for the first time. Install Rockbox using RockboxUtility or | ||
81 | download the latest daily build and uncompress it into the root folder | ||
82 | of the iPod. | ||
83 | |||
84 | Windows only: | ||
85 | |||
86 | - If iTunes is installed: | ||
87 | . Configure iTunes: Summary -> Options -> check "Enable disk use". | ||
88 | |||
89 | - If iTunes is not installed: | ||
90 | . You need a DFU USB driver for your device. To check if there is a | ||
91 | valid USB driver installed, put your device on DFU mode and choose | ||
92 | one of either: | ||
93 | a) Use Windows Device Manager to verify if you USB DFU device is | ||
94 | present. | ||
95 | b) Use mks5lboot tool running "mks5lboot --dfuscan", common output: | ||
96 | . When the DFU device is found and a valid driver is installed: | ||
97 | [INFO] DFU device state: 2 | ||
98 | . When the device is found but there is no driver installed: | ||
99 | [ERR] Could not open USB device: LIBUSB_ERROR_NOT_SUPPORTED | ||
100 | . Then the device is found but driver is not valid (probably a | ||
101 | libusb-win32 driver is installed): | ||
102 | [ERR] Could not set USB configuration: LIBUSB_ERROR_NOT_FOUND | ||
103 | . If there is no valid DFU driver installed, try one of these: | ||
104 | a) Use Zadig (http://zadig.akeo.ie/) to build and install a WinUSB | ||
105 | (libusb.info) or libusbK driver for your device. Note that | ||
106 | libusb-win32 (libusb0) drivers are not valid for mks5lboot. | ||
107 | b) Use Apple Mobile Device USB driver (included with iTunes). | ||
108 | |||
109 | Command line install: | ||
110 | |||
111 | - If you are using iTunes on Windows, close iTunes and kill (or pause) | ||
112 | iTunesHelper.exe before entering DFU mode. | ||
113 | |||
114 | - Put you device on DFU mode by pressing and holding SELECT+MENU buttons | ||
115 | for about 12 seconds. | ||
116 | |||
117 | You can notice when the device enters DFU mode running the next command | ||
118 | to scan the USB bus every second (press Ctrl-C to abort the scan): | ||
119 | mks5lboot --dfuscan --loop | ||
120 | |||
121 | - To install or update a bootloader, build the DFU installer and send it | ||
122 | to the device: | ||
123 | mks5lboot --bl-inst /path/to/bootloader-ipod6g.ipod | ||
124 | |||
125 | When the DFU imagen is loaded and executed, the device emits an 'alive' | ||
126 | tone (2000Hz/100ms). When the bootloader is successfully installed then | ||
127 | a dual tone beep sounds (1000Hz/100ms+2000Hz/150ms) and the device | ||
128 | reboots. If something went bad then 330Hz/500ms tone is emited and the | ||
129 | device reboots. When three 330Hz tones sounds, it means that the NOR | ||
130 | got corrupted and the device must be restored using iTunes (should not | ||
131 | happen). | ||
132 | |||
133 | - To remove a previously installed bootloader, build the DFU uninstaler | ||
134 | and send it to the device: | ||
135 | mks5lboot --bl-uninst ipod6g | ||
136 | |||
137 | If USB access is denied, try to run the mks5lboot tool using a privileged | ||
138 | user (i.e. Administrator or root). | ||
139 | |||
140 | |||
141 | Dual-Boot | ||
142 | --------- | ||
143 | |||
144 | The purpose of this program is to provide dual-boot between the original | ||
145 | firmware and the new (rockbox) firmware. | ||
146 | |||
147 | The button press check is done ~800 ms. after power-up or reboot, then: | ||
148 | |||
149 | SELECT + MENU: resets the device after ~5 seconds, then if SELECT+MENU | ||
150 | remains pressed the device enters DFU mode after an | ||
151 | additional period of ~8 seconds. | ||
152 | SELECT + LEFT: enter OF diagnostics (after ~7 seconds). | ||
153 | SELECT + PLAY: enter OF diskmode (after ~7 seconds). | ||
154 | SELECT + RIGHT: enter bootloader USB mode. | ||
155 | MENU: enter OF | ||
156 | Hold Switch locked: enter OF (see below for details). | ||
157 | Any other combination: launch Rockbox. | ||
158 | |||
159 | Switch current firmware: | ||
160 | |||
161 | Tries to behave like ipod Video, see http://download.rockbox.org/manual/ | ||
162 | rockbox-ipodvideo/rockbox-buildch3.html#x5-290003.1.3 | ||
163 | |||
164 | Apple is the current FW: | ||
165 | - Stop playback and wait a few seconds for hard disk spin-down. | ||
166 | - Press and hold SELECT+MENU, after ~5 seconds the player hard resets, | ||
167 | release the buttons when the screen goes black. | ||
168 | |||
169 | Rockbox is the current FW: | ||
170 | - Shut down the device using "Long Play" key press. | ||
171 | - Once the device is powered off, there are three ways to enter OF: | ||
172 | 1) Press and hold MENU button for at least ~800 ms. | ||
173 | 2) Turn on the Hold switch immediately after turning the player on, | ||
174 | it must be done before "Loading Rockbox..." message appears (~3 | ||
175 | seconds from power-on). Be careful, if the hold switch is locked | ||
176 | when Rockbox starts then your RB settings will be cleared! | ||
177 | 3) You can also load the original firmware by shutting down the | ||
178 | device, then clicking the Hold switch on and connecting the iPod | ||
179 | to your computer. | ||
180 | |||
181 | |||
182 | Single-Boot | ||
183 | ----------- | ||
184 | |||
185 | Use --single option if the Apple firmware is not installed on your iPod | ||
186 | and/or you want to force the installation of the bootloader to use Rockbox | ||
187 | as unique firmware. The single-boot installer writes the bootloader on the | ||
188 | NOR with no previous check, the original Apple NOR boot is destroyed if it | ||
189 | exists. | ||
190 | |||
191 | To build the DFU single-boot installer and send it to the device: | ||
192 | mks5lboot --bl-inst --single /path/to/bootloader-ipod6g.ipod | ||
193 | |||
194 | |||
195 | Compilation | ||
196 | ----------- | ||
197 | |||
198 | Needs libusb > 1.0 installed, tested on: | ||
199 | |||
200 | Linux: gcc-4.9.2 + libusb-1.0.19 | ||
201 | Windows XP: mingw32-gcc-4.8.1 + libusbx-1.0.15 | ||
202 | OS X 10.11: clang-7.3.0 + libusb-1.0.20 | ||
