sorry, but no. If I sell some product of mine, I'm not sure someone could TRY to make readout of CPU flash contents. In fact, its not so bad. Its closed. That's all. But, if he or she tries to do so, it will damage contents of the FLASH! And device became unusable. It's done without any confirmation or smth. that tries to stop user of damaging the device. So, again, I tell you - this is unsafe behavior of the reading program. It must WARN! not DAMAGE! Feel differnce?

Hello, Is there any way that allows to detect secured (protected to Level 1) CPU? Because if I try to connect to locked CPU using J-Flash. It automatically unlocks CPU (which cause full erase of CPU contents) . I think this behavious is unsafe if we do not have CPU flash contents and just want to perform attepmt to read it. So, is there any way to detect or not erase CPU if it is secured, but just tell user "CPU is locked"? Many thanks

Hello, You are right. J-link reads it. I thought there was a standard 20-pin jtag connection there, but there is not.

I found out that XDS110 cant even start when I connect TCK pin to my CPU installed on my board. When I desolder it, and place into testboard - everything works fine.

Hello, I've received the LaunchPad with TMS570 on board. I'm trying to connect to the TMS570LS1224 installed there, but with the same results. Quote: “ ERROR: TMS570/RM4x (connect): Can not find ICE-Pick (IRLen mismatch) MS570/RM4x (connect): Can not find ICE-Pick (IRLen mismatch) TMS570/RM4x (connect):Can not find ICE-Pick (IDCODE mismatch).

I also receive the following: " Connecting ... - Connecting via USB to J-Link device 0 - Target interface speed: 12000 kHz (Fixed) - VTarget = 3.280V - ERROR: Bad JTAG communication: Write to IR: Expected 0x1, got 0x0 (TAP Command : 10) @ Off 0x5.

Hello, I'm trying to connect via JTAG with TMS570LS113 (same as LS1114) It giving me the same result: " - Target interface speed: 12000 kHz (Fixed) - VTarget = 3.287V - ERROR: Bad JTAG communication: Write to IR: Expected 0x1, got 0x0 (TAP Command : 10) @ Off 0x5.
