I made a mpc8308 test board according the mpc8308-rdb, now, I can connect the board via USBTAP, can
change gpio status through CW8.8 ，but when i test flash mx29lv640bttc-90，the flash programer can
show" flash erase complete" ,actually i can see the lcs0 voltage status is always high
3.3V.obviously it doesn.t work . How can i deal this problem.thank you
What is the difference between your board and MPC8308-rdb board?
Which target initialization file you are using?
Also, the device requires Reset Configuration - which source you are using for reset configuration?
thanks for your response, the initialization file is 8308mITX_init.cfg and 8308mITX.mem,the JTAG Configuration file is 8308mITX_rev1_HRCW_jtag.txt. Today I test the DDR2 using USB TAP, it passed. and When I connect board via USBTAP, choose no initializaion file, establish the connection, then when I kill the connection,the lcs0 port seems work well. However,when i restart the board or reconnect the board using initialization file,the phenomenon vanish.
I am also using MPC8308 RDB Board. But I could not able to do u-boot debugging because this board have some reset issue when using with JTAG probe.( USB TAP with Code warrior 8.8)
Have you faced similar issues ?
Pls Gentle man.
( Also We have modified the reset Circuit as per Design Check list suggested by Freescale Tech Support.)
