Carprog before reprogramming Mcu connect to 12v.

[forumoto]

we need video tutorial on how to configure this jlink, i bought one from china but just dont know how to configure and what to set and steps by step involve to click on the software page in other to make a successful flash, you can see images of h-jag that has images but jlink do not, show pictures

[helmi reguig]

configure steps by step plaese thanks connections for me not works

[2xded]

I did not check the connection.
Do you executed erase the chip before connecting the J-Link?
Regards.

[radrad10]

Yes erase the chip before connecting the J-Link, connect carprog as described, connect the 12v and reprogram.
First run software J-Flash ARM V4.26 and click:
file -> open project -> folder ProjectFiles ->select the file AT91SAM7S256.jflash (these are the suggested settings JLink for Mcu AT91SAM7S256).

Later click:

open data file (select the file with dump)

carprog must be connect to 12v,

click:

target -> connect -> program.

good luck

--------------------------------------------you connected with carprorg ????? thanks

-pin55 from ARM- must lifted or not

[helmi reguig]

My connection between carprog and jtag is:

1-vdd
3-NRST
5-tdi
7-tms
9-tck
11-gnd
13-tdo

[gwee]

erase again, this time over 5 mins, will be ok :)

upgraded mine with J link v8 also

[pandokrator]

-pin55 from ARM- must lifted or not

pin 55 from ARM must lifted from pcb,after solder a smal wire on pin,give 3V about 10sec (for erase ARM),
after solder wire on gnd (pin 55 Always lifted from pcb) and start programing ARM.
easy job m8 :-)
Br

[helmi reguig]

iy have this messge sam7:failed to measure CPU speed after switch to main oscillator

[pandokrator]

have you the right port settings ?
i use LPT jtag ,never i use usb jtag :-(

lift pin55,connecting to VDD (3Volt) ,conect miniUSB,push Search button from your program,when find ARM,remove miniUSB,
connect lift pin55 to GND,,,

helmi reguig (http://www.digital-kaos.co.uk/forums/members/252253-helmi-reguig/) my friend, listen

Remove the AT88SC eeprom from the board
1. first you must erase Mcu on carprog how to do it:
-pick up and connect pin 55 Mcu to Vdd on carprog and connect car prog to 12v for 5 seconds (Mcu will be cleared)
and remove the pin 55 wire from vcc. The pin 55 must remain disconnected until the programming process is done.
2. connect carprog to jlink:
carprog ---------------- jlink
tdi --------------------- pin 5
tdo -------------------- pin 13
tms -------------------- pin 7
tck -------------------- pin 9
gnd ------------------- pin 20
nrst ------------------- pin 15
3. connect carprog to 12v and jlink to usb
4.reprogram Mcu using the J-Flash ARM software, how to do it:

First run software J-Flash ARM V4.26 and click:
file -> open project -> folder ProjectFiles ->select the file AT91SAM7S256.jflash (these are the suggested settings JLink for Mcu AT91SAM7S256).

THE BEST MAN WHO HAS PROVIDE THE BEST ANSWER TO THE LONGED ASKED QUESTION OF SETTING UP JLINK IS THIS GUY: RADRAD10. thank U

[forumoto]

264789 this is the error that comes, even though i make good connection to the carprog pcb, with 12 and all wired but cannot connect, please ADVISED, or else need to make the home made jtag with the printer port and use the h tag software rather, show me image of your jlink connection to carprog radrad10

[forumoto]

Some advise is needed for making the homemade Jtag with LPT port, please want to know the the value for the resistors, and should it be Kohms or ohms

Now looking back at the description...I program my clone with pin 55 connected to erase on carprog board when programming and apparently nothing bad happened.

[Multipla]

HI friend, when I program carprog all is Ok when I put the tool in USB and open software ( usb not detected) What will happen?

[forumoto]

for me i need to buy new jlink as the repair does not still get connected to the CP

[Multipla]

Forumoto while I have program okay CP,,, but now does not recognize usb.

[ominimicu]

Let me get this. i can update my carprog , and after unlock it?
i ve used J link before in NXP inside kess!
