Issue with using user pipe on PSoC 6

I already have the pipe set up and the endpoints registered according to CE223820 example code.

On CM0+ I call this function every 32ms:

CM4_IPC_CALLBACK_ENCODE_AUDIO is 2, which corresponds to the index of the callback function that I am calling on CM4.

Here is the definition for pT_ipcSendToCm4()

On CM4 this callback function gets called

I have a global int named i which is initialized to 0.

If I have the following code in the callback function:

I see the light on the device flashing blue and green, which is as expected, since i is incremented every time we send a message from CM0+.

However, if I have this code in the callback function:

And this code in the main loop of CM4:

The light on the device stays green and does not change, as if i is not being changed at all. I tested changing different global variables inside an ipc pipe callback function. I observed that the changes to the variable are reflected in the callback function but nowhere else within the scope of CM4.

Why is this happening? Is there something different about the IPC pipe interrupt from other interrupts? How is the memory being handles in this case?

UPDATE: I worked around this issue by declaring all of the memory on CM0 and passing pointers to CM4. So all the memory that M4 uses are statically declared on M0.

Hi,

I think that the issue that I am having is similar to https://community.cypress.com/t5/PSoC-6-MCU/Unable-to-reprogram-CY8CPROTO-062-4343W/td-p/192710.

When I purchased the board, I tried quickly to see if any messages can be seen in the console, but I didn't see any. I tried only once and ignored the issue thinking that the jumpers were not in correct places, so I figured i'll ignore the issue and program the board with AWS instructions. Perhaps the board is faulty, but I don't know how to check. To this date I am still not able to see any messages on the console when booting the board.

I tried flashing with both the FreeRTOS codebase downloaded per instructions and cloning the repo from https://github.com/cypresssemiconductorco/amazon-freertos (checked out tag 202007-MTBAFR2041) and got the same results.

The project seems to build successfully (see first log below ), but I am getting errors during programming (second log).

The jumper positions are:

J14: VCC 3v3/2v5

J15: Connected

J16: 1v8

J26: Connected, after I programed the credentials.

All other jumpers are connected.

KitProg light is solid. I also updated the KitProg firmware.

dmesg log when connecting the board:

The Open Documentation Team is looking for a few great beta testers. People interested in a single place to find their documentation and a place where it will be updated on their feedback. The Cypress Community has always been a place of collaboration with you, our users, and we’d like to extend an invitation to give us feedback on this new platform between now and January 10th, 2021.

The first documentation platform we’re opening is for PSoC 6 and AnyCloud customers and offers all the documentation you, the developers, need in one place. The Open Documentation platform allows users to find all the development documentation in one place, complete with real-time updates from our software and support teams based on inputs and questions from our developer community. This creates a responsive, easier to use platform for you to find everything throughout your development process.

This platform will host the latest version of the documentation along with continuous updates from our support organization based on questions from you, our Community members. We look forward to hearing your feedback on this beta PSoC 6 and AnyCloud book and collaborating with you on better documentation going forward.

Jump over and test out the PSoC 6 and AnyCloud platform here.

Let us know here what you think of the platform. Test out the in-documentation feedback tool too. We’d love to hear any other documentation books you would like us to build.

Thank you for being a part of our commitment to continually improving our developer experience! I appreciate your help in making this the best tool we can.

Thank you,

Robyn Weil

HI  Cypress:

      we want to updated the firmware though the UART interface , can you help to provide the IAP demo code of PSOC62? TKS;
