Hi Infineon.

I think PSoC 4100S Max supports DFU(device firmware upgrade).

Can PSoC 4100S Max update firmware with serial interface even when chip protection setting of below link is “Protected” or “Kill”?

https://github.com/Infineon/cce-mtb-psoc4-flash-and-chip-protection

Can user use both DFU and chip protection(“Protected” or “Kill”) features at the same time?

Best Regards.

The Project_timing.html file is not being generated in PSOC Creator. How can I fix this?

Hello.

With CYBLE-202011 module a project made in PsoC-3.3; I need to convert it to CYBLE-202007 module. As a first step, I must compile the project in PsoC-4.0 or a higher version because the CYBLE-202007 module is not available in a lower version. Secondly, I change the module in the Device Selector section and then set the voltage to 3.3V (because the operating voltage of CYBLE-202007 is max 3.6V). When I do these, Bluetooth broadcast is interrupted. I add the following parts to the code.

#define CYREG_SRSS_TST_DDFT_CTRL 0x40030008

switch(eventCode)

    {

        case CYBLE_EVT_STACK_ON:

            CY_SET_XTND_REG32((void CYFAR *)(CYREG_BLE_BLESS_RF_CONFIG), 0x0331);

            CY_SET_XTND_REG32((void CYFAR *)(CYREG_SRSS_TST_DDFT_CTRL), 0x80000302);

            CyBle_GappStartAdvertisement(CYBLE_ADVERTISING_FAST);

            break;

Bluetooth broadcast came, but the system is not stable. Some devices do not see the broadcast. I would like your support regarding this issue.

Thanks.

Hi Infineon.

IMO accuracy for devices with temperature range from -40deg to +105deg is ±2.5%(red frame).

Device is PSoC 4100S Max.

https://www.infineon.com/dgdl/Infineon-CY8C41xx_PSoC_4_MCU_PSoC_4100S_Max_Based_on_Arm_Cortex_-M0_CPU-DataSheet-v06_00-EN.pdf?fileId=8ac78c8c83cd30810183fc2ad1424e75

If this device is used from 0deg to +85, will IMO accuracy be guaranteed by ±1.25%(blue frame) instead of ±2.5%?

Even if device has worst IMO accuracy spec(in other words, temp range is -40deg to +105deg), is IMO accuracy spec guaranteed to be lower than ±2.5% if used over a narrower temperature range(for example, -20deg to +105deg)?

Best Regards.

I'm trying to sort out SFLASH.  I'm using a CY8C4247LTI-M475.  I'm not sure if it has SFLASH or not.  I want to store a small amount of data that doesn't get wiped out when the code is updated.  I read 0x0FFF_F200 and get all zeros like something is there.  I read 0x0FFF_F300 and I actually get some non-zero values.   I call a function that should be writing to SFLASH row 0 and then I read 0x0FFF_F200 again and it is still all zeros.  Later I read 0x0FFF_F300 again and it is now all 0s.

Most of the SFLASH references I've seen are about BLE.  I'm not sure if it is a BLE specific feature or not.

Am I just doing something wrong, or am I trying to use a feature the chip doesn't have?

Thanks,

Wilton

P.S.:Not much response during the holidays. 

The first question that I'd appreciate someone who knows (such as an employee) is whether the CY8C4247LTI-M475 has  SFLASH?  If it doesn't then there's no point in continuing.  If it does, I can share some code to see what I'm doing wrong.  But that piece of information appears elusive.
