Hello,
I am trying to write RCW to NOR Flash of a T4240RDB Rev2 board with a broken RCW on EEPROM.
I am using codewarrior "CodeWarrior_PA_10.5.1"
I created an new Bareboard project with target T4240RDB Rev2.
I am using the SRAM download project with T4240RDB_RCW_1666_733_1867-rev2.0.txt as jtag initialization file.
T4240RDB_init_sram.tcl Target initialization file. and T4240RDB.mem memory initialization
Using CodeWarrior TAP over ethernet.
The switch settings of the T4240RDB board is done as written in T4240RDB_eabi_README.txt
SW1: 1100 SW2 :1111 SW3:1111 SW4:1111
And the jumper1 JP1 is at JTAG mode.
When I start the debug sessin I got the message:
"CCSProtocolPlugin: Failed to correctly configure the JTAG chain."
Does anybody have any idea about this case, since T4240RDB is the reference board of NXP not my custom design, in my opinion I think it must be easy to connect and burn a new RCW .
Does anybody have any idea, any help will be appreciated.
Instead of using jtag for RCW I solved the problem by writing the RCW to SD card and boot from SD.
Then I wrote the RCW to eeprom from uboot.
