PSoC™ 4 Forum Discussions

Dear community,
Working on a project based on CY8C4046LQI-T452 reached the stage where we need to think on the production automation and more specifically on the chip programming. For my great disappointment, there seems to be no options to do a CLI programming using the cheaper(KitProg3) option. From what I have read, reached to the following conclusion:

-Modus Toolbox CLI is not suitable as the make/build option is not desired
-PSoC Programmer does not support the target and is not going to
-mtb-programmer does not have CLI option

The last option left is using a J-Link.
Would appreciate you suggestions

Kind regards

Hi, Teams. 

I have a question.

Can you support CY8CKIT-002 for WIN11? 

If it can be used, what is the difference in functionality from MiniProg4?

Hi,

I am doing a research project using CY8CKIT-042 PSoC4 Pioneer Kit (CY8C4245AXI-483).  The prototype device is powered from a battery of 40mAh capacity. After the normal mode operation when I power OFF the device, the uC enters into deep sleep power saving mode. From the deep sleep mode when I connect charger for charging the battery or press the power ON key then uC exits from deep sleep mode and enters into normal mode.

However in an extreme case, the battery was weak while the time I powered OFF the device then in between the deep sleep operation state the battery was fully drained and there was no power source to the device and uC wad fully turned OFF.

After the above scenario, when I connect a power source to the device the expected behaviour is that the device should turn ON automatically due to the reset signal that appears on connecting the power source. However, in some scenario the device didn't turned ON and a re-flashing of the uC was required for turning ON and resuming the expected behaviour.

Can anyone suggest some root cause for this behaviour and what could the possible solution to avoid it?

Thanks in advance.

Hello together,

in the description of the HSIOM_AMUX_SPLIT_CTL-Registers I found that there seems to be a switch to connect the Bus to GND/VSSA. The switch is named SWITCH_AA_S0  (or BB for Bus B). In one of my application it would be helpful to use this switch to discharge the whole bus.

Is there any documentation how this switch works? I tried to activate it, but I didn't see any success.

Unfortunately I did not find any details in the TRM for PSoC4100PS. Also I can't find any details in the code or in the analog routing graphics.
