请教大家一个问题

我现在做的boot程序在跳转app程序的时候，如果boot程序和app程序都没有使用中断的情况下可以正常跳转，但是boot程序或app程序有一方面使用中断的话就会进入到debug，boot程序或app程序单独运行时没有问题。下面按照串口中断举例。

调试状态下会卡在下图位置：

我想知道是哪个地方设置的不对或者少设置了什么地方。

Hi,

I am doing a research project using CY8CKIT-042 PSoC4 Pioneer Kit (CY8C4245AXI-483).  The prototype device is powered from a battery of 40mAh capacity. After the normal mode operation when I power OFF the device, the uC enters into deep sleep power saving mode. From the deep sleep mode when I connect charger for charging the battery or press the power ON key then uC exits from deep sleep mode and enters into normal mode.

However in an extreme case, the battery was weak while the time I powered OFF the device then in between the deep sleep operation state the battery was fully drained and there was no power source to the device and uC wad fully turned OFF.

After the above scenario, when I connect a power source to the device the expected behaviour is that the device should turn ON automatically due to the reset signal that appears on connecting the power source. However, in some scenario the device didn't turned ON and a re-flashing of the uC was required for turning ON and resuming the expected behaviour.

Can anyone suggest some root cause for this behaviour and what could the possible solution to avoid it?

Thanks in advance.

IFX_INTERRUPT(OS_CAT2_General_Handler,0,6);
IFX_INTERRUPT(OS_CAT2_General_Handler,0,5);

why i can't install same handler in different priority. It's logically can do as ARM architecture as the processor only use the priority to get the Handler start, i need a solution for installing the same handler (ISR) in different priorities to handle CAT2 interrupts in my project and i can't upload the project as i have a signed NDA.

Hello everyone! I have some questions about tle9879 driver bldc, pwm frequency selection, and would like to get answers.

For the same motor, the motor inductance parameter is measured and the results are measured:

Frequency 1khz ------Ls-900uH Lr-0.8Ω

Frequency 10khz ------Ls-880uH Lr-5.4Ω

Frequency 15khz ------Ls-850uH Lr-10.2Ω

Frequency 20khz ------Ls-830uH Lr-16.1Ω

If you look at it according to impedance, the lower the frequency, the lower the impedance, then the greater the output capability of the motor; conversely, if the frequency is high and the impedance is high, then the output capability will be reduced.

But the actual test to see, the results are not so, ccu6- >T12 is also on the pwm setting frequency 10hkz when the carry capacity is very weak, a little bit of load may be held back; and 20khz than 10khz carry capacity is much stronger. Here may have something to do with the renewal current, but exactly what is not understand.

Anyone who understands the relationship between frequency and torque would be grateful for an answer!

Hello Team,

I am LG India team,  

we are using I2C driver provided by Infineon team to LG Korea team,

in I2C driver, Cy_SCB_I2C_SlaveGetReadTransferCount( ) is available which Returns the number of bytes read by the slave since the last time Cy_SCB_I2C_SlaveConfigReadBuf() is called. 

we calling this function before Cy_SCB_I2C_SlaveConfigReadBuf().

but we found its not reading correct values.

could you test once share procedure to use.

We are looking for an MPU socket with below part number to use on a customer's prototype board.
・CYT4BFBDJS (272pin BGA)
Could you please tell me the supported socket part number of this MCU?

Thank you & Best regards,

顧客の試作基板上で使用するための、下記型番のMPUソケットを探しています。
・CYT4BFBxJSに (272pin BGA)
このMCUに対応するソケットの型番を教えて頂けますでしょうか？

よろしくお願い致します。

Dear forum:
I write hex file to flash by cypress programmer.
I can write the hex file normally, but when I open the cypress programmer,

but why the Chip protection is UNKNOWN?

Thank you.

Comment: My soft don't touch the eFuse address.

Hello 

Can we allocate 2 nodes on MULTICAN_CONFIG_0, and operate all message objects of both the nodes using only one CAN_Rx and CAN_Tx through transceiver??
