Welcome to the Infineon Developer Community

Hello, 

dear friend:

The background for this question is: App needs to transfer some data to bootoader, and App jump to FBL via 'soft' reset. 

Following solution works fine for NXP MCU:

1.allocate the variables to share date between App and FBL in a special section named 'NoInit_RAM'

2. In startup.s (created by compiler automatically),  bypass the copy initiliazation for section 'NoInit_RAM'

For TC367 +ADS1.8,  step 1 is completed successfully, 

variable counter_receive is allocated to section 'NoInit_RAM' and its address is 0x70020000 like below

But I don't know how to do step 2. 

From my know-how, the ADS created file Ifx_Ssw_Tc0.c , and call function Ifx_Ssw_doCppInit() to perform variable initialization. 

/* Initialization of C runtime variables and CPP constructors and destructors */
Ifx_Ssw_doCppInit();

The function _c_init() in lib libcs_fpu.a is called to do the actual initialization, it's impossible to change logic of _c_init()

IFX_SSW_INLINE void Ifx_Ssw_C_InitInline(void)
{
extern void _c_init(void);
_c_init(); /* initialize data */
}

I guess the '__A0_MEM' is used by _c_init() to initialize the global variables,  so

The dsram0 size is changed from 192K to 128K, limited to range [0x7000000, 0x70020000]

But variable counter_receive is still initialized to value = 3

Could you please give me a solution to bypas the section 'NoInit_RAM' initialization?

the lsl and map file is attached for your reference. 

thanks and BR

Dear ALL,

the datasheet says the supply voltage can be extended up to 28V.

what is the trade off?  the datasheet does not mention any further application notices about this.

I guess the inductive load capability maybe reduced due to the higher input voltage.

looking forward your feedbacks.

thank you.

What is the maximum input voltage for EVAL_IMD700A_FOC_3SH board? 

The operating voltage of the EVAL_IMD700A_FOC_3SH and IMD700A are totally different. So I am confused. 

The application note of EVAL_IMD700A_FOC_3SH says, input voltage is 12 to 24V. Same side, the datasheet of the IMD700A says, operating voltage is 5.5V to 60V. 

My question is, If I am give the voltage more than 24V, what would happen?   

I attached the screenshot of the application note of EVAL_IMD700A_FOC_3SH and datasheet of the IMD700A for your reference.

Kindly helping me to clarifies the doubt.

Hello guys,

I have an urgent need to buy few pieces of CY8C4745AZI-S413. Seems that major distributors and Infineon also have no units in stock. I need only few parts, I would need 3 or 4 to complete a product, it is not a mass production product, we made only 3 to 5 units per year but it has a value of several thousand Euros. One of these units has to be delivered before Christmas (it is related to Christmas) so, not finding these parts quickly not only will block the product delivery but also its need.

If anyone has in house some pieces of CY8C4745AZI-S413 I will be happy to buy or quickly substitute them from the order I already placed (but the delivery is planned in the 2nd half of December). Also if someone knows where I can buy them I will be happy to be adviced.

Thanks,

Massimo

Hi all,

In my project used the Modbus Tcp IP protocol with cypress ic CY8C4246AZI-L445 in that i want the c library API for commuication . if anybody khow these ,pelase help me

thank you

I just installed the XDPP1100 GUI (Build 8334) and connecte the XDPP1100-Q024 socket debug board via USB007A dongle (FW v65). The GUI responds extremely slow if I check the "Enable Telemetry Update" in the Options menu. It will become normal when "Enable Telemetry Update" unchecked. How to solve this problem?

Hello,

I am trying to use your IKW15N120T2 IGBT in my work for showing the effect of different design approaches on IGBT lifetime. I want to use the model described in the attached picture, which require some parameters based on accelerated testing data as I understand.

Please let me know if these parameters are already available in any of your documents and if not, please consider providing me with the parameters if possible.

Regards,
Ahmed
