PSoC™ 4 Forum Discussions

Hi,

We use PSoC 4.2 BLE 256KB Module of CY8CKIT-143A as daughter board to build our hardware prototype. The hardware prototype is

functional. And then we replace the PSoC 4.2 BLE 256KB Module daughter board by using CY4248LQI_BL583 chip( the chip used for

the daughter board) to make the merged board and referring your PSoC 4.2 BLE 256KB Module schematics and BOM, the rest of feature are

the same. We have the issue to initialize the BLE hardware.

The CY4248LQI_BL583 chip programming and most the rest of feature on the merged board are functional. When the program is running the

BLE initialization, the system is hung. We use the SWD tools to capture the stack when the system hung and attached the screen captured

image from the Cypress Creator tools.

Since the same program is work with the hardware prototype, the issue is happened on the merged board, this is mostly possible related

to the hardware. I'd like to get the hint for the possible reasons to cause such issue and the way to fix this issue.

Regards,

Tony

Hi all,

I am trying out the example of FixedStack OTA bootloading for PSoC 4 BLE device. I am doing the steps as described but I got error in step 11. Bat file is giving error: Can't find utilities folder "C:\Program Files(x86)\Cypress\PSoC Creator\4.1\PSoC Creator\import\gnu\arm\5.4.1\bin\arm-none-eabi-nm.exe" Please check if path to PSoC Creator specified correctly.

I am using CY8C4248LQI-BL583.

Someone please help me on this as soon as possible. I am a beginner for the PSoC application development.

Is there any sample code for CAN interfacing available for PSOC 4100 s plus (CY8CKIT-149)amily microcontroller?

Please provide links.

Hi All,

Running on CY8C4247AZI-M485,

I have an application (bootable) and a bootloader.

I followed instruction in "Emulated eeprom v2.0" and got everything running smooth using "checksum excluding sector".

I can now use emulated eeprom in my bootable application.

Now I would like to access the emulated eeprom "checksum excluding sector" from within the bootloader project, - how would I go about it?

thanks

Dan

Hello all,

my colleagues in the test department found a flash corruption case

Our device is connected to the battery of cars, so it is powered at 12 V; it has also a bootloader

The test is: turn on device, wait for a while, turn off (to 6 V, that is off), wait, repeat.

After a variable amount of time the device stops in the bootloader (it turns on a blue led)

I used psoc programmer to download the two images (corrupted: left)

As you can see, at address 1FFC0 the content is different (all zero in the corrupted case, erased?)

From the map file I got:

.cyloadermeta  0xf0000000       0x40 .\CortexM0\ARM_GCC_541\Release\cybootloader.o

                0xf0000000                cy_meta_loader

                0x0001ffc0                cyloadablemeta_start = cy_project_type_app_for_stack_and_copier?((LENGTH (rom) - CY_FLASH_ROW_SIZE) - CY_METADATA_SIZE):((LENGTH (rom) - (CY_FLASH_ROW_SIZE * (CY_APPL_NUM - 0x1))) - CY_METADATA_SIZE)

.cyloadablemeta

                0x0001ffc0       0x40

*(.cyloadablemeta)

.cyloadablemeta

                0x0001ffc0       0x40 .\CortexM0\ARM_GCC_541\Release\cymetadata.o

                0x0001ffc0                cy_meta_loadable

Can you tell me why this can happen? That is, when bootloader/bootloadable change that flash row?

Best regards

Massimo

Hi ALL：

  What's the AD value when a pin of the MCU was set to a AD function but connect nothing for Psoc S2？
