SYSCONFIG: AM263P4 sysconfig GPIO "Qual Sel" option seems to not work

Part Number: SYSCONFIG

Tool/software:

Using SysConfig 1.23.0+4000

How do you change the "Qual Sel" option on sysconfig?

Before:

After:

I was expecting the tool to add PIN_QUAL_XXX flags to ti_pinmux_config.c::gPinMuxMainDomainCfg[]. But nothing changes regardless of what value I choose for "Qual Sel".

Please help me understand what I am doing wrong here.

Also, is there a way to configure the sampling period using SYSCONFIG?

Again, thanks for the support.

Hi Huey,

Apologies for the delay as the GPIO expert was unavailable.

This is a valid bug, the logic for Qualification Selection(Qual Sel) has not been implemented in syscfg.

I have created a bug for this and it will be fixed in next release.

Meanwhile more details on this feature can be found in TRM at 13.1.1.4.4 Input Qualification

In regards to the section you posted, please clarify if the documentation needs updating.

tw(IQSW) should = 5 x 10ns = 50ns. The line above says tw(SP)=10ns not 5ns.

Also, shouldn't the output from qualifier signal go back high after 6 samples of the GPIO signal? The diagram shows 5.

Regards.

Agreed Huey,

HW team also confirmed this.
