Dear sir,

I am developing  AURIX TC2xx bootloader and application, and I have some question to ask.

The environment is using AURIX Development studio, and blinky led example in ADS,  and Triboard.

1. Does Infineon provide the user guide or appliction note to teach how to  implement?

2. Now I try to modify the flash size, address(vector table, pfls, bmdh, reset...) in Lcf_Tasking_Tricore_Tc.lsl for bootloader(256KB) and application(768KB). In bootloader, set the command like below jump to application, and it works.

__asm("movh.a a15,#0x8004\n"
"\tlea a15,[a15]0x0020\n"
"\tji a15");

But when my bootloader code size is big, jumping to applcation will be failed. I think it may caused by disbabling interrupt(IfxCpu_disableInterrupts() ;)before jumping to application.  My question is before jumping to application, should I disable interrupt? or what is reason to cause jumpling to application failed?

3. Now my applicaion start address is like below, and if I implement software reset in application, and where it will reset jump to? And is the setting of reset run addr corrcet?

memory pfls0
{
mau = 8;
size = 768K;
type = rom;
map cached (dest=bus:sri, dest_offset=0x80040000, size=768K);
map not_cached (dest=bus:sri, dest_offset=0xa0040000, reserved, size=768K);
}

group reset (ordered, run_addr=0x80040020)
{
select "*.start";
}

Thanks.

Hello,

I'm using TC275, ADS 1.9.8 and Tasking compiler

I'm building a bootloader project and it is working as expected with the default linker.

Now I want to limit the address range occupied by the bootloader app to [0x80000000: 0x80014000] of pFLASH0 

Below are the changes I did tot he linker

Full linker is attached as well.

when i run the code, at some point it gives me the following trap

Based on traps documentation, this means 

Class 3 : Context Managemetn error

ID 4:  FCU Free context list underflow.

And it seems that this is happening because there is not enough space for TRAP table for CPU0, is that correct ?

How can I fix this issue ?

Hi Infineon Experts:

I want to know for TC3XX series, Is it possible for one GTM_ATOM channel trigger multiple VADC Channels/ VADC Sync Groups?

Thanks for your support in advance.

1.我选用TC397 的AN14引脚做了一个电压采样，需要计算漏电流对采样精度的影响

2.查看DS我不知道选取哪一个漏电流 ，是从Table 3-15 Class D中150nA的还是Table 3-16 ADC Reference Pads中的7uA?

Hi AURIX support team,

In my old system (using the 16-bits C167 Infineon family chip), it has the Conxtex Pointer feature to change the RAM address .

I would like to implement this feature also in my new Aurix TC234 system. However I cannot find the corresponding part for this feature. Do you have any suggestions?

Best regards,

Hello， I am currently developing the SWAP function of TC397 and have encountered a confusion. I need to consult. As shown in the above figure, can I understand it this way: programming the content of Flash once (updating the App) requires switching between A Bank and B Bank once, and operating UCB once. Therefore, if each TC397 updates the APP by switching between Bank A and Bank B, it can only be updated 400 times? This is obviously not enough, is it because I misunderstood the SWAP limit function?
