I am working on a Flash Write routine which is part of a boot loader for the CY8C27243.  I am using Application AN2100 as a starting point. I have all aspects of the bootloader working except for Flash Write.  After many days of debugging I have narrowed it down to the Supervisor ROM Flash Write sequence which uses the M8C SSC instruction. 

Here is a simplified sequence used to access a supervisor ROM routine as found in FLASHAPI.asm which is part of AN2100. This is part of the temperature table access routine and is a very simple use of the supervisor ROM and should work.

push A   ; save the State variable
push X
mov X, SP   ; copy SP into X
mov A, X     ; mov to A
add A, 3     ; create 3 byte stack frame
mov [0xF9], A   ; save stack frame for supervisory code
mov [0xF8], 0x3A   ; load the supervisory code for flash operations
mov A, 6    ; load A with FLASH_TEMP_TABLE_LOOKUP rom code
SSC          ; SSC call the supervisory code
pop X

Code execution does not return after the SSC instruction. I am assuming it is halting for some reason.

I have double checked all of the parameters and can't figure out what I am doing wrong.  Can SSC only be called when the M8C is in a certain mode ?  I have been able to read Flash successfully since that routine uses the absolute ROM read instruction ROMX which avoids an SCC. I wish there was such an easy way to do a write.

I have been working on this bootloader for nearly a month now and need to finish this before new product release.  

 I tried creating a project for the CY8C6245 processor on PSOC Creator 4.4.

  It is not in the list of allowable processors.  The PSOC 62 processor version  246 and 247 parts are there, but not the 245.

  What can I download to support the CY8C6245 on PSOC Creator?

I have just started with this board. I installed EZ-USB HX3PD Configuration Utility but in the Update Manager, it is showing me network error. I exited from Update Manager and then restarted from start menu, it opens EZ-USB HX3PD Configuration Utility window. I can't find any document to upload their. 

Can anyone help me with this?

Thanks

I would like to create a bootloader bootloadable combination that I could flash without the PSoC programmer, so I want to be able to flash the bootloader and the bootloadable without the programmer. Is the Combination Project my best bet? Can I do a combinations project where the bootloadables  are not splitting the memory? Or is there a different way to do this like the In-Application Bootloader?

Dears.

We are using GX3 to implement “ethernet to usb new module”.

This module is HW-implemented in USB 2.0 Only (Vbus, D+, D-) and When this module is hooked up to the computer,

PC device driver “Cypress GX3 Superspeedto Gigabit Ethernet BridgeController” is brought it up successfully in Network Adapter, device manager as the following. Then, when I tried to run “GX3 EEPROM configuration Utility” and press the "program" button to write configuration paramters like Mac address anD so on to the EEPROM, it pops up the error like “Open Device Fail”.

Could you tell me what happened inside of it ? Please give us any tips to get through it.

Thanks,

WonjinHan.

Hi All,

Merry Christmas and happy holidays.  My professional development project has hit a block.

Purchased a CY8CKIT-064S0S2-4343W kit and am working with ModusToolbox v2.2.0. 

I have hit an issue when trying to provision the device.  I get the following error when I try to do the provisioning as spelt out in the the Provisioning Guide documentation.

Everything seems to be ok but it fails with this error message

"

2020-12-29 14:24:59,073 : C : ERROR : Early Production Units detected, please get earlier version of tools by running 'pip install --upgrade --force-reinstall cysecuretools==2.1.0'. Check the log for details

Error: Failed processing! "

This error is also returned if I try and run the entrance-exam command.

Based on the responses, I am sure that the hardware is communicating with my pc.  I can't actually run the earlier version of cysecuretools as when I try that, I get a stack of python errors about being unable to build the wheel for cryptography which use PEP 517 and cannot be installed directly. 

So I would like to get things working with all the current versions of ModusToolbox etc.    Please help, it seems to be a pretty pathetic way to be failing as I am just trying to get the demo code to work at this stage 😞

Here is the response to entrance-exam.

The response when attempting to provision is similar.

The rest of the provisioning response is the same as for the entrance-exam.

Thanks in advance for any help.  Cheers!

hello,

i've succesfully tried and reproduced the example called "qspi_read_write_using_sfdp".

When i'm importing the rights function in my project, the init function fails (cy_serial_flash_qspi_init).

When i'm digging into the details, it fails when calling Cy_SMIF_MemInit which return CY_SMIF_SFDP_SS0_FAILED

i've compared everything, and i'm not able to find what i'm doing wrong.

is there anybody who experienced the same issue ? thanks

How do you delete watchpoints in PSoC Creator?  In debug mode they are not selectable and right click does nothing.  When not in debug mode the windows does not appear.

Hi

I am making a connection to 2 different phones at the same time and trying to setup 2 simultaneous SCO links using HFP. For this to work I need at least one of the connections to route through the APP, I can see that it can be done by using:

wiced_bt_dev_status_t voice_patch_status =  wiced_bt_sco_setup_voice_path(&hfp_client_voice_path_setup);

WICED_BT_TRACE("Voice path setup status: %d\n\r", voice_patch_status);

I have inserted it right after:

result = wiced_bt_hfp_hf_init(&config, hfp_client_event_callback);

In the init of hfp.

And the rest is:

void hfp_client_sco_data(uint32_t ltch_len, uint8_t *p_data)

{}

static wiced_bt_voice_path_setup_t hfp_client_voice_path_setup =

{

              .path = WICED_BT_SCO_OVER_APP_CB,

              .p_sco_data_cb = &hfp_client_sco_data

};

I get status 0 Success but when I make the connection, I get a BTM_SCO_DISCONNECTED_EVT after BTM_SCO_CONNECTION_REQUEST_EVT instead of a BTM_SCO_CONNECTED_EVT.

I have also tried it in the Audio_Headset_and_Speaker example, there uses the bt_hs_spk_lib component, so here I have done it by:

bt_hs_spk_set_audio_sink(AM_UART);

And then the component should do the rest but same result, a disconnect.

I have been looking around but can’t find what I am doing wrong, do I need to include or setup something more to get it to work?

Is there an example project that uses wiced_bt_sco_setup_voice_path to APP?

Is there an example project their setup multiple SCO connections?

I use:

• CYW920721B2EVK-02
• Eclipse with ModusToolBox v2.2.0
• Bluetooth SDK version 2.8.0
• A headset with microphone
