Hello,

I am trying to write user configurations to MBR3 in the following procedure:

1. Read the SYSTEM_STATUS(0x8A) register

2. If SYSTEM_STATUS (bit0) is 0, write configuration parameter to MBR3 (according to Register TRM)

3. If it is 1, nothing is done.

However, after doing this process, the SYSTEM_STAUTS register will be 0, but the configuration will remain at the factory default.

I think that the SYSTEM_STATUS register is 1 at the time of shipment from the factory, and will be 0 when writing something.

Is this correct?

If not, please tell me when the SYSTEM_STATUS register will be 1.

Regards,

Hello, I'm using the PSOC4 4200 to sequence the power rails for an FPGA. I would like to run the PSOC in Unregulated External Supply to I can only provide 5V to the device. The 5V is applied as soon as power is applied to the board.

Is this the correct configuration for the 28-SSOP CY8C4244PVI-442?

Thank you very much,

Joe

I am using CY8CKIT-042 BLE.

I want to return the KIT firmware to the purchase state.

Please give me advice.

The device is a PSOC 4200. I'm using the 8-bit IDAC for CAPsense and the 7-bit iDAC in standard configuration.

According to the resource meter, the uC has both these iDACs.

When I compile the project with just the 8-bit iDAC it works without a problem. However, when I add the 7-bit iDAC to the design, it fails to compile. The error shown is  'unable to find a solution for the analog routing' That's it. There is no further description.

What could be the problem?

When my central receives a scan from the client, it has the client's address in a CYBLE_GAPC_ADV_REPORT_T data structure.  My central can connect to the client using this address.  But in my client code, I get (I assume) my client's address by calling CyBle_GetDeviceAddress.  THese two addressed don't match, why?

I see there have a been a few similar queries before where other modules have generated this Build error but none of the answers given in those queries help me understand this issue.

Background:

I have a Solar Powered IoT Device Kit (with BLE module CYBLE-022001. I tried to build the Simple_BLE example but get the error "Section .cy_checksum_exclude size exceeds specified limit." When you double click on the error message it opens up the Linker script file cm0gcc.ld but does not highlight which line.

Based on other online searches and comparing this to the LED_ONOFF example, which does compile/ build ok, it appears to be related to this line here

CY_CHECKSUM_EXCLUDE_SIZE        = ALIGN(640, CY_FLASH_ROW_SIZE);

The LED_ONOFF example has

CY_CHECKSUM_EXCLUDE_SIZE        = ALIGN(0, CY_FLASH_ROW_SIZE);

So my question is, where did the "640" come from in the Simple_BLE example. How/where was this set.

I know that if I go to the Bootloadable component in TopDesign and change the "Checksum exclude size (bytes)" to 640 it does work and I can build my project.

But still no idea why.

Any advice will be greatly appreciated.

Thanks.
