Hello, my name is Zdravko,
Lately i purchased ADSP-CM408F EZ-KIT Lite with J-Link LITE v8.2. After i plugged J-Link for first time, it asked me for firmware update.
Here is the information after the firmware update:
Firmware: J-Link ARM Lite V8 compiled Oct 29 2014 09:03:16
Hardware: V8.00
So, i started IAR Embedded Workbench and tried to debug and download to the processor with JTAG/SWD, but i always get these errors:
*** SWD interface
- Connecting via USB to J-Link device 0
- Target interface speed: 2000 kHz (Fixed)
- VTarget = 3.371V
- ERROR: DAP error while reading AIRCR / CPUID register
- ERROR: Failed to connect.
Could not establish a connection to target.
*** JTAG interface
- Connecting via USB to J-Link device 0
- Target interface speed: 2000 kHz (Fixed)
- VTarget = 3.371V
- ERROR: Bad JTAG communication: Write to IR: Expected 0x1, got 0x0 (TAP Command : 10) @ Off 0x5.
Error while identifying Cortex-M device. Wrong AHB ID. Expected 0x04770001, found 0x00000000
CM40x/CM41x connect: Can not find TAPC (IRLen mismatch)
- ERROR: Failed to connect.
Could not establish a connection to target.
The processor on the kit is ADSP-CM408CSWZ-AF, the nearest model that i find in J-Link' s configuration settings is ADSP-CM408BSWZ-AF.
The processor is ok and running with it's demo program, i checked the cable it's ok too. I downloaded the newest software from your site and i get the same error.
Is it possible, if J-Link was with some special firmware for this kit and after it updated itself to the newest version it can't work ... or is some other problem?
