Hi, all

      checked from previous discussion saying that "using Nor Flash with file system need to erase all before write or create a file", Is that still true for emFile system?

     my project need to write log to a file on a Nor Flash, and keep the log files until it is erased. If I must erase Nor flash before I update the log, it is a big problem. 

   Thanks.

Hello,  I have been working on a project that includes both AP and STA mode for PSoC6. 

I successfully achieved to configure WiFi operations by using WCM and WHD libraries. However, when I tested what happens when I shut down the AP, which the PSoC connected, I got a stack overflow exception in debugging. When I trace the error, I found that the PSoC6 tries to reconnect to the AP with JOIN_RETRY_ATTEMPTS number of times. Then, if this number is exceeded, a timer thread is set to some backoff time to start to retry attempts. When this timer is finished, handshake_error_callback function is called second time and it starts retry attempts but in the first attempt, there is a stack overflow.

Device is CYSBSYSKIT-DEV-01. WiFi Connection Manager release v2.3 and WHD release is v2.1.

Thank you.

In PSoC Creator, we can design BLE on Dual CPU. there is an option in configure "Contoller on CM0+, Host and Profiles on CM4".

Now we start use MTB3.0. How to implement this?

Thanks!

Hi Everyone,

I am writing a program that opens a .cycad2 file and sends the data over UART. In the program I format the flash rows using the Infineon-AN213924_PSoC_6_MCU_Device_Firmware_Update_Software_Development_Kit_Guide-ApplicationNotes-v09_00-EN user guide and from a record of a successful DFU programming over UART which shows the DFU protocol and formatting.

I have successfully programed a device using the boot loader app from PSOC creator. I am using the AN213924 example project with App0, and App1 as a working model to test my code. 

My question is how is the CRC-32C calculated on page 54 of the guide for the 0x49 DFU command (Program Data)? I have a function to calculate CRC-32C, but I'm unsure how the row of data in the .cycad2 is broken down to generate the CRC-32C bytes? Are all the bytes in the row added together, then a CRC-32C is performed on the result? Is the flash row broken into 4 byte 32 bit number, then added together for the CRC-32C? I don't see how it is specified in the document. All the other data packets with the DFU 0x37 command use a checksum which I have been able encode and matches the UART data I have observed.

I see these 4 bytes while watching the a successful DFU programming with App1 on the UART bus with the 0x49 command: 0x15, 0x61, 0x56, and 0x48 which I think is 0x48566115 to match the byte order of the other byte fields. 

The row that generated this CRC-32C is below from the app1 .cyacd2 file: 

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

How is this CRC-32C evaluated? This is the last part I need to figure out to get my remote DFU updated program working.

Hello all,

I have created the project using the CYBLE 416045-2 where the ADC continuously samples data and as soon as 240 bytes of data is acquired it is sending it through notification packet over the BLE (Project is attached herewith)

The connection is established properly, and I am able to send data continuously. I am trying to measure current during this entire process. I have attached my multi-meter with a jumper on the J8 jumper on the board as marked by yellow on the picture attached.  The J2 jumper (marked by blue) decides the voltage level on the board. With 3.3 V I am observing current of 117.3mA however when I open the J2 jumper (board running on 1.8V) the current I am observing is around 1.2mA however in this case I am not able to find the BLE connection of the board on the Cy smart app or even on the BLE dongle. 

Can anyone guide me is this the correct way to measure current for this board? If so, what am I doing wrong such that the current is going to 117.3mA in 3.3V case because it is WAY TOO MUCH above the board specification. 

Also, if there is any wrong on the programming side could you guide me on how to reduce current for this case. I want to run the board on minimum possible power and minimum possible current cause it needs to run for days on a single cell of battery.

Thanking you,

Anik Sengupta

I cannot get the EEPROM working right in my program.  I ran the EEPROM demo project and it works but I cannot use the same code because the compiler rejects it:

That is really tiny, hope it is readable.  Anyway the compiler says that it cannot assign to the userFlashStartAddr.  Maybe this has something to do with it being const, but in the example this works.  After some trial I discovered that the example was using EEPROM version 2.0 and I was using 2.2 - Aha! I said, but changing to 2.0 makes no difference.

if I instead use EEPROM_Init ((uint32_t)EEPROM_em_EepromStorage). the init returns success, but every attempt to write to the EEPROM fails with the failure return value.  

So  It seems that I have to use the middleware Cy_ functions, but the complier will not accept the start address...

(Oh, and I am enabling global interrupts before the init function is called.)

Any help???

Thanks, Russ
