AURIX™ Forum Discussions

近日，我购买了一块KIT_AURIX_TC397_TFT板子，里面是官方默认的固件， 我看说明书里通过板子的Mini USB连接PC （Windows 10 )，就可以识别到板子，但是我用usb连接后，板子TFT屏幕正常点亮，只有D106 (V_UC)、D104 （SS2）灯亮和P13中的一颗灯在闪烁，但在PC设备管理器里面找不到Infineon JDS DAS COM和Infineon JDS DAS Debug，安装DAS软件也无法识别，这种情况应该怎么处理?

Hi Team,

Compiler : Tasking

Controller: TC36X

I am getiing below error while  compiling, my intention is not to clear  one global variable on start up  by using #pragma noclear

#pragma noclear: use of --no-clear / #pragma noclear is not allowed with --eabi=N or --eabi-compliant option

So I removed the compiler option --eabi-compliant  instead of that I used --eabi=BCFHSW. Compilation is through.

If I use compiler option as --eabi=BCFHSW, any side impacts on creating binary files? and I have no idea what is BCFHSW.

Hello, I meet with a problem when flash to B bank using  bootloader. After having flashed, the B bank filled with 0xFF, if config A bank as active bank, the A bank  filled  with oxFF,  do you know some possible reasons?

DPLL的RAM2C区域用来保存TRIGGER信号的特征，相应的内存寄存器为Memory DPLL_ADT_T[x],但是直接使用这个寄存器在ADS中无法识别此寄存器，求助。

1. We are aware about UCB DBG to lock debug interface using 256 bit Password and unlock it.

2. We would like to know if Aurix TC32LP has the mechanism to lock JTAG permanentely ? Here we may not need to unlock it once locked. May be some kind of bit in registers which triggers permanent locking of JTAG debug interface.

Currently, we are checking out if there is any possibility to permanently lock JTAG.

From user manual, I did understand that to do a JTAG lock with PSW protection we need to update PROCONDBG register, then, after reset, the new values will be applied from UCB_DBG_ORIGIN and UCB_DBG_COPY and JTAG will not be accessible anymore.

This registers, UCB_DBG_ORIGIN and UCB_DBG_COPY, are located at addresses 0xAF402400 and 0xAF403400 for TC32LP.

In PROCONDBG register we are disabling access to JTAG by setting DBGIFLCK to 1. By doing so JTAG will be disabled at next reset.

Currently, we are using UDS services to provide a password and to lock/unlock JTAG access. So, in this way if we accidentally lock it we’ll be able to unlock it.

What we’d like to know if it is possible to lock JTAG interface permanently without any way of unlocking it no matter what way. Is there this kind of possibility to do so?

这里描述说实现中断嵌套需要配置中断优先级组，但是我没看到有介绍分组的文档，请问中断嵌套要如和实现？谢谢

Hi,

 I can write 8 bytes of data in DFLASH memory using page address. I need to write a single byte of data at any memory address.

Is it possible to write a single byte of data at any memory address location?

Thanks
