#Segger embedded studio debugger never hits breakpoint serial#The above mentioned kernel provides already a serial port( ). There is no offical Linux 4.1 for the Neo.Īdditionally take a look at: (Linux part) and (FreeRTOS part) to get a serial port and a lwip capable network interface (I only tried the serial port) running. You can use the operator ‘&’ to mask the value you wish to break on. For example, sp < 0x1000 will breakpoint when register sp is accessed and its value is less than or equal to 0x1000. The operators <, >, >, >,, and can be used similarly.Rpmsg is not support by Linux 3.14 but 4.1. The expression x 4 will breakpoint when x is accessed and its value is 4. In the IDE screenpic you can see the list of bitfields for the RCC AHBENR register, complete with the bitfield description in Gvim, partially reproduced below. The FreeRTOS does not have support for MCC but for rpmsg. For instance, Words for every one of the 413 registers and every one of the 3044 register bitfields for all 34 peripherals in the STM32F051 are created automatically. The Arduino stuff uses MCC to communicate with the Linux part. The communication via virtual serial port! NXP supports it offically so what can possibly go wrong?! My idea was to get rid of the Arduino stuff and use FreeRTOS. After this change the breakpoints worked. I used a different linker script (OCRAM or TCM can't remember). I have other projects that work just fine but I have no idea what setting would cause this. Optimizations are set to none, debugging level set to full, but 'No Locals' is all I ever see now. But apparently it had something to do with the place where the firmware is executed. I have a project that suddenly stopped showing any local variables in the debugger view. Have a look at: Ĥ) I had problems using breakpoints. #Segger embedded studio debugger never hits breakpoint update#It is a daisychain.Ģ) Hitting a breakpoint or pausing execution is for BOTH cores.ģ) Invest in an NXP LPC Link 2 and update the firmware with the Segger one. I have looked at the Udoo Neo and had, as far as I can tell, similar intentions.ġ) As fas as I have read, the JTAG interface ist for both A9 and M4. ![]()
