JTAG Could not detect a flash controller (Jasper)

[indianx]

Hi,

Iam not getting any results since 4-5 days. I have checked everything 5-6 times and i do not see any wiring mistake or bad solder.
I have resoldered everything 2-3 times still nandpro2.0b and nandpro3 wont read it.
Installed also the driver port95.exe on windows XP without any error message.

I have 20-30 threads and iam not sure if i missed anything. When i plug the db25 cable into lpt port and run

nandpro ltp: -r16 orig.bin

i get this error message (tried it with nandpro2.0b and nandpro3)

NandPro v2.0b by Tiros

Testing LPT device address:0378
Testing LPT device address:0278
Testing LPT device address:03BC
Could not detect a flash controller
Can Not continue

Not sure if the port95.exe installed correctly. If i go device manager to check the lpt driver it shows windows driver date from 2001.

I have followed this guide:

Please help.

LPT is an old and unsupported method for reading the NAND.

I suggest you get a NAND-X or a J-R Programmer.

hmm shouldn't that tutorial work? Didn't it used to work?

maybe iam using the wrong nandpro version or port95.exe driver version.

Tutorials and methods get old.

J-Runner does everything you need, but I don't think it supports LPT NAND reading/writing.

Find your local reseller here.

XCONSOLES are very reputable resellers and they are based in the US I think.

thanks, i dont want rgh just simple jtag and run homebrew. no extra online etc.
i heard rgh is not good. long turn, boot, loading time etc.

money is little tight there is no way to do it with nandpro?

if your going JTAG or RGH is not your choice to make, it depends on what CB you have. get a safe way to dump your nand and check your CB.

thanks guys. I knew i did not did any mistake. i just tested the rj45 joiner looks like that thing was faulty.
sorry i should have tested sooner. would have saved me lot of time and solder

i wired directly and now i can read it.

dam faulty items.

Thank you.
