After downloading the HEX file to an MCU such as TC275TP, I want to check the integrity of all memories to see if the download was successful.

Although the checksum method is used, not all memory is calculated, and there is a memory area that is out of the checksum calculation range, such as the user data area.

How to check the integrity of all memory, including downloaded and undownloaded areas, to see if the values I want are included?

Hello, I am developing a bootloader using the tc389 board.

First , I apologize first for my poor English.

From 0x80000000 to 0x80007ff  is bootloader section,

from 0x80008000 ~ i use application. 

my last bootloader code is 

1.version

Ifx_Ssw___setAddressReg(A0,0xA0008004);
__asm("ji a0");

2.version

pProgResetHandler = (void(*)(void))(*((u_addr *)0xA0008004)); 

pProgResetHandler();

but it  doesn`t work!

always i meet trap_bus_Error 

and that is  "Program Fetch Synchronous ERROR"

so i think this problem is like protecting flash memory ?

but i can`t find register  

please , help me 😞 

Hello,

I am having an issue to connect debugger port after updating the PFLASH ucb.

Here are the pflash UCB configurations:

PROCONPF 80000000

RPRO Configured

PW0 03020100 PW1 07060504 PW2 0B0A0908 PW3 0F0E0D0C
PW4 13121110 PW5 17161514 PW6 1B1A1918 PW7 1F1E1D1C

CONFIRMATION 43211234 UNLOCKED ^confirm+

Looks like debug access is locked and PFLASH protection is enabled (once RPRO bit is set, the SSW will lock the debug interface ). Is there any way to recover the card?

Note:

HSM is disabled

Hi everyone:

I had configured in application project Ifx_Cfg_SswBmhd.c file the start address is oxA00008000:

bmhd0~bmhd3's configuration in application project is same,

const Ifx_Ssw_Bmhd bmhd_0_orig = {
0x00FE, 
0xB359, 
0xA0008000, /**< \brief 0x004: .stad: User Code start address*/
0x31795570, 
0xCE86AA8F,

}

and in the bootloader project the start address is 0xa000000, bmhd0~bmhd3's configuration in bootloader project is same,

const Ifx_Ssw_Bmhd bmhd_0_orig = {
0x00FE, 
0xB359, 
0xA0000000, /**< \brief 0x004: .stad: User Code start address*/
0x31795570, 
0xCE86AA8F,

}

 I want to know that whether the configuration is reasonable or not. thank you.

Hi Infineon:

       We had designed Ecu Based on AURIX TC387. Now we need bootloader for reprogramming. But to Develop a new bootloader start form zero is a big challenge for us. we want a bootloader demo based on TC387. thanks a lot!

Hi Community,

Hi Infineon Team,

What is the input impedance for analog-input pins AN16 and AN18  of the Aurix TC377TB-96F300S AA ?

I didn't find information about it in the datasheets

Infineon-AURIX_TC3xx_Part1-UserManual-v02_00-EN

Infineon-AURIX_TC3xx_Part2-UserManual-v02_00-EN

Are there Application Notes  / additional resources on Infineon website about analog-input of Aurix controllers?

My goal is to use these pins to connect to a voltage divider and measure voltage divided from a 24V power supply. Current draw from the 24V supply should be 100mA. Thus I like to know the input impedance, so I can calculate the value for R6 for the case that 24V corresponds to a 2.5V signal input an AN18 like the attached picture shows.

Thank you for your time and have a great weekend!

Sebastian.
