Thanks a lot... it will help us a lot to avoid to use the reset pin. Regards Christian

I have a question I am using the flasher for ARM... and J-Link commander detects my microcontroller (Cortex - M3). When I try to erase the flash, I got an error (CPU is not halted). - ERROR: CPU is not halted - ERROR: Timeout while checking target RAM, core does not stop - ERROR: Failed to erase sectors On our circuit, we didn't connect pin 15 to the reset pin of microcontroller. Is it a problem? Our reset is connected to a R-C circuit. Also, I tried to use the flasher as a standalone... and whe…

In my application, we can wake up only by generate an external interrupt. It wakes up the CPU during few seconds... during this period, I can start again the application! Other point, I don't know if it's related to this problem. Our reset pin (NRST) is connected to a RC circuit. It's not connected to JTAG connector pin 15. I don't it could be a problem! Regards Christian

It was few months I didn't come here... I would like to tell you that we have this problem when the Cortex is in sleep mode. We have to wake up the cpu when we start the debug session. Otherwise, you will see this error.... I think the J-Link doesn't wake up the cortex itself... Regards Christian

Hello, I continued with an other board and I got once again the famous AHB ID error. So I need to revive my board as soon as possible. I don't understand what I did to produce this problem. It works properly until I got this error. I think that since I used the multimeter to measure the current, I got this error. The multimeter has a fuse of 300 mA. Does the current exceed 300 mA during programming? Nevermind, I need asap to revive my board please. Christian

I found out the problem. You don't have to call printf function when J-Link is not connected and not running. I removed all printf call in my IAR project and it works very well! Hope help you! Christian

It is our own board that we have done. We connected BOOT0 and BOOT1 to boot in user mode. Regards Christian

Hello, I downloaded the application in my target device (Cortex - ST) with J-Link. I run the application with IAR debugger and it works. When I unplug the JTAG cable, it continues to work. But, I would like to understand why when I power off and power on my board, the application doesn't start. Is there any configuration to do in order to start the application? Christian

The device I have connected is JLink for ARM processors from IAR systems Version 6.0. The target device is a STM32F101 (Cortex from ST) Thank you, It would be appreciate to have an answer today if possible. Thank you Christian

Hello, When I try to start a JLINK session with IAR or segger's application, I got this error... Wrong AHB ID (15:3). Expected 0x04770001 (mask 0xFFFFFF0F), Found 0x000000F0... I Unplug-Replug JLink power and it doesn't work I unplug replug Target device ad it doesn't work I reinstall drivers and restart PC... doesn't work too... So, I don't have any idea to fix this problem Regards Christian
