The Issues are strictly limited for the reporting of problem encountered with the software provided in this project.

Describe the set-up
NUCLEO-G071RB + X-NUCLEO-SRC1M1
Describe the bug
Within the context of a sink application. If a PDO is described with 0 current, then the PDO comparison will always fail. e.g.
SNK PDO = 5V 0A
SRC PDO = 5V 3A
Will return a PDO mismatch even though technically this isn't a mismatch unless its a rule violation I am unaware of.
How To Reproduce
Create a SNK PDO with a 0A current level. have a SRC PDO with matching voltage and >0A available.
Additional context
I am not yet familiar enough with github to post exact links but
Projects/NUCLEO-G071RB/Applications/USB_PD/SNK1M1_Sink/USBPD/Target/usbpd_dpm_user.c
line 1176
if ( (snkvoltage50mv == srcvoltage50mv)
&&(snkopcurrent10ma <= srcmaxcurrent10ma))
{
currentrequestedpower = (snkvoltage50mv * snkopcurrent10ma) / 2; /* to get value in mw */
currentrequestedvoltage = snkvoltage50mv;
}
currentrequestedpower will end up as 0 because snkopcurrent10ma is 0. When currentrequestedpower is 0 it is considered a mismatch. But that's not true. since the requested current is less than the available current.
