1 | 4 | gnutoo | To compile nuttx-bb with sercomm, do the following steps: |
---|---|---|---|
2 | 1 | gnutoo | |
3 | * Clone osmocom-bb and nuttx-bb, they must reside in the same directory and you shouldn't change the name of the osmocom-bb directory. |
||
4 | {{{ |
||
5 | git clone git://git.osmocom.org/osmocom-bb |
||
6 | git clone git://git.osmocom.org/nuttx-bb |
||
7 | }}} |
||
8 | * Put the gnuarm(for 64bit) or the codesourcery(for 32bit) |
||
9 | in your path(there is a problem with gnuarm for 32bit). |
||
10 | * Compile osmocom-bb as usual |
||
11 | {{{ |
||
12 | cd osmocom-bb/src |
||
13 | make |
||
14 | cd ../../ |
||
15 | }}} |
||
16 | 6 | gnutoo | * Configure nuttx-bb: |
17 | 1 | gnutoo | {{{ |
18 | cd nuttx-bb/nuttx/tools/ |
||
19 | 2 | gnutoo | ./configure.sh compal_e88/nsh #for compal_e88( gta02 and Motorola W220). |
20 | 1 | gnutoo | ./configure.sh compal_e99/nsh #for compal_e99( motorolla c155 ) |
21 | 6 | gnutoo | }}} |
22 | * Modify your configuration(nuttx/.config): |
||
23 | {{{ |
||
24 | -CONFIG_SERCOMM_CONSOLE=n |
||
25 | +CONFIG_SERCOMM_CONSOLE=y |
||
26 | -CONFIG_STDIO_LINE_BUFFER=y |
||
27 | }}} |
||
28 | |||
29 | * compile nuttx-bb: |
||
30 | {{{ |
||
31 | 1 | gnutoo | cd ../ |
32 | make |
||
33 | }}} |
||
34 | 5 | gnutoo | * nuttx.bin is ready for beeing loaded like any other firmware (Loading nuttx-bb is not different from loading osmocom-bb, refer to the pages related to osmocom-bb for informations on how to load a firmware in your phone.) |
35 | |||
36 | == Running == |
||
37 | Once you loaded nuttx-bb you should see the following appearing on sercomm: |
||
38 | {{{ |
||

||
61 | To interact with it run the loadwriter.py script that can be found in nuttx/drivers/sercomm/loadwriter.py in the nuttx sources. |
||
62 | {{{ |
||
63 | sudo ./loadwriter.py |
