I've (mostly) implemented the dump eventlog command but I ran into an
issue which I haven't been able to figure out yet. Wondering if I am
doing something obviously wrong here.
In the usb log the process begins by writing the command 7300 0000. The
device returns the number of expected log entries after the JL_ACK
response.
This is the code, and it works fine (error handling removed):
packet.GetEventlog();
m_socket->Packet(packet);
m_socket->Receive(response);
MAKE_JLPACKET(jpack, response);
uint16_t count = be_btohs(jpack->u.response.expect);
To get log entries the command 7400 0200 is used. This time there is
no JL_ACK response, but instead, another write occurs which just has
a 16 bit integer value which increments and starts from zero.
Following this is the JL_ACK and the log entry data.
Now Barry seems to know when to send this 16 bit integer packet since I
don't do any special handling for this. However the problem is that the
value 2 is written instead of starting from zero (might not be an
issue) but never increments.
I use a loop to get the entries and inside the loop I have:
packet.GetEventlogEntry();
m_socket->Packet(packet);
m_socket->Receive(response);
MAKE_JLPACKET(jpack, response);
uint16_t size = be_btohs(jpack->u.logentry.size);
...
// parse the data in the response
I've attached what the exchange looks like using javaloader.exe.
Any ideas?
