Hi all
Does anybody knows the schematic (pin connections, max3232 connection ) in
order to make a programming cable, for program an RCM (5xxx,6xxx) mini core
using a legacy pc com port ?
Thank you in advance

9-pin Dsub 232 Transceiver R6K
Connector
---------- ----------------- ---------------
2 - Rx ------> R_IN --> R_OUT -----------> 50
3 - Tx <------ T_OUT <-- T_IN <----------- 48
4 - Status <---- T_OUT <-- T_IN <----------- 47
5 - Gnd -------> GND

| o
----> -/ o---------------------------> 49 (SMODE)
Switch 1
(Close to put into programming mode)
The RS-232 cable needs to be a full NULL Modem cable.

Thank you very much Steve.
I will try it today .
The 49 pin (SMODE) can be connected like this ? 9-pin Dsub 232 Transceiver R6K Connector
---------- ----------------- ---------------
6 - DSR ------> R_IN --> R_OUT -----------> 49 (SMODE) )
in order to let DC10 switch the rabbit to programming mode ?

No. Because when the PC enables the serial port it will put the
rabbit in programming mode. The SMODE can't be connected to any
pin in the serial connector.

Hi Steve
Finally i've make this thing to work
The connections are
PC max3232 rabbit 6000
----- ---------- -------------
RX --<----------------------| |----<------------------------ TXA
TX ---------------------->--| |---------------------------->-RXA
DTR--------------------->--| |---------------------------->-/RESET_IN
DSR+DCD--<--------------| |-----<------------------------STATUS
SMODE tied to 3.3V thru a 10K pullup resistor
I'm wondering if, in the pcb we have a header in which when a connector is connected ties together the reset and the smode signals (after the rs232 transceiver), this will work like the programming header in series 2xxx,3xxx ?
The problem is that in this connection we must reboot the module with smode connected to 3.3 v to see that is in programming mode.
You have the same behavior in your circuit?

You don't need to reboot if you toggle the Reset line while SMODE is
set.

Is there a way of doing a full reboot, i have the serial setup on a pcb for
if web update fails. but i find when i upload from the web interface. i
have to power cycle before the new firmware is loaded from flash to ram.

if web update fails. but i find when i upload from the web interface. i
have to power cycle before the new firmware is loaded from flash to ram.

Have you tried forceSoftReset()?
Alternatively, you can probably get a "harder" reset using the virtual watchdog (max 15 sec hit) and locking yourself intentionally in a closed loop.

Hey All,
Just one BIG precaution on DTR to the RCM6000 (or any, for that matter).
We used an FTDI USB/serial to acheive the same thing + a jumper on SMODE to switch between prog/run modes, but this applies to any permanent (on-board) interface (as opposed to a removable prog cable).
- In prog mode, DTR must be connected to the CPU reset-in, as Dynamic-C needs to reset the processor.
- In "run" mode, there are two problems:
1. By default, DTR is cycled by the FTDI driver on connection, which means your processor is reset whenever you plug in to a PC. The solution (posted by FTDI) is to change the port setting via Device Manager to un-check "Serial Enumerator" and check "Disable Modem Ctrl at startup". However, if someone forgets to do this, you will get an unwanted reset on connection.
2. Terminal programs such as Hyperterminal and Putty always assert DTR, even if you select NO flow control. This holds the CPU in a permanent reset state.
