Hello,
I am working on a project with custom board featuring CY43012 radio chip. I try to start a WIFI access point using my device.

I ported WHD library, and have SDIO part working. The firmware is being uploaded to CY43012, firmware starts, then I have succesfull communication with device (write/read to function 2).

Unfortunately my program aways fails at the same moment during execution.
The parts not working are sending data with SDIO on:
/* Register for interested events */
/* Set the SSID */
/* Set the passphrase */

In that parts of code I get an error:
whd_bus_sdio_cmd53:874 cyhal_sdio_bulk_transfer SDIO_BYTE_MODE failed
cyhal_sdio_bulk_transfer SDIO_BYTE_MODE failed
Error during SDIO receive, whd_bus_sdio_read_frame failed at 615
ioctl_sleep timeout
Command failed in whd_wifi_init_ap at 382
Command failed

After running whd_cdc_send_ioctl() function.

I connected a scope to my board and figured out that before firmware upload the data lines are on high state when not used. After uploading firmware It switches to low state. After writing data to device with BLOCK MODE the inactive state of data lines are going back to high. After that the next command execution fails.

Do you have any ideas what might be an issue?

Thanks,
Piotr

I found an issue with my implementation of cyhal_sdio_bulk_transfer function. By code error I was rounding down the block count number when the result was not a natural number.

Hi,

From your response, I understand that the bringup is successful, but the code is failing at the time of execution, right? can you attach some logs to get a better picture?

Thanks

Hi,

the bringup works fine, but I can not start the Access Point. Writing SSID in whd_wifi_init_ap() function fails.

the console log of execution:

Additionally I added a simple test before and after this error: 

testResult = whd_bus_sdio_read_register_value(whd_driver, BUS_FUNCTION, 0x02, 0x02, &value);

In both cases, before and after cyhal_sdio_bulk_transfer failiure testResult is 0, but the value is received from device only before the error.

Hello,

I also changed the WHD library to the newest version. It didn't change a lot. I still get an error while setting up an access point or while I try to scan local networks. Console log:

Additionally I tested writing register to BUS_FUNCTION. Before this error the operation is possible, but not after the error. 

whd_bus_sdio_write_register_value(whd_driver, BUS_FUNCTION, 0x02, (uint8_t)1, 0);
whd_bus_sdio_read_register_value(whd_driver, BUS_FUNCTION, 0x02, (uint8_t)1, &value);
