The logging/debugging code is generic enough to move it into libosmocore
while keeping OpenBSC specific definitions in openbsc itself.
This commit uses the logging support present in libosmocore-0.1.2,
you will have to update your library to this version.
Currently one has to put -w in front of -f to really write the
firmware file to disk. Change the config handling to first take
all parameters and then execute on them. This means -f can now
be used with any other parameter.
Use the start address inside the header entry, the start is relative
to the surrounding SDP record which is located in our base offset, when
writing it out also ignore four bytes of something (crc?).
* The length of the table is not at a fixed position. We will need
to read the offset, seek there, read the data, convert it to the
host endianes.
* Prepare the code to work with offsets of 0...
This library is intended to collect all generic/common funcitionality
of all Osmocom.org projects, including OpenBSC but also OsmocomBB
The library currently includes the following modules:
bitvec, comp128, gsm_utils, msgb, select, signal, statistics, talloc, timer,
tlv_parse, linuxlist
msgb allocation error debugging had to be temporarily disabled as it depends on
'debug.c' functionality which at the moment remains in OpenBSC
* Do not issue the restart right aways if we have OML IP or
software load in the queue (hint, we need a real queue of operations
to carry out... with one big state machine)
* Change the signal_data of ipacc ACK/NACK to contain the msg type
and the bts pointer.
* Issue a restart for software load and OML and use the BTS pointer
we got out of the new signal data.
We are filling sw_load1 with the information found with type
0x1000 and sw_load2 with type 0x2001. It appears from the protocol
traces that these information is not extracted from them. We also
need to include the \0 from the string.
With this firmware flashing seems to work.
* text3 seems to be a version as the text content starts
with a 'v'
* move the sdp_firmware into the ipaccess.h and declare
the function. The headers are returned through a list.
* The second magic number is only a short and it is
the same for all of my cases
* This also means that the first and second header
are the same which means the unknown 8 byte are
header and file size... and the 122 bytes are
actually multiple strings (just all empty on the
outermost SDP). Adding the strings left us with 120
bytes so we have two bytes of unknown usage..
* This is now capable of parsing outer and inner SDP
files and print their header.
* The internal SDP appears to have a different magic number
than the first entry and a slightly different packet format
* There are 8 byte of binary for at the beginning and the header
ends with a table pointing to some strings and then the actual
firmware follows.
* We currently only parse the strings of that header.
The something3 points to the next start of the SDP
entry. The four bytes in front of the " SDP" are not
known and just discarded. Prepare to be able to
recursively parse the SDP header...
I must have picked in the wrong section of these
files... There are some kind of header entries
that are all 138 byte long and this is the total
length...
Strictly speaking we would only need to start the Site Manager
and could probably start flashing afterwards but it is more easy
to have one config path...
This will mostly work like the downloading in bs11_config
and is based on the bs11_config state machine as well. Once
it is working we can see how to unite both implementations.
