S32G POWER UP

longfeiwang — Thu, 18 Nov 2021 03:06:40 GMT

We encountered a problem. The communication rate between S32G and SJA1110 was changed to 1G on the RDB2 development board. After a period of normal operation, it was inexplicably unreasonable. I couldn't find the reason. Then I remembered the EVB development board. For the problem, I unplug the 12V power connector of the RDB2 development board and leave it for a while, then plug it in and power it up and the communication is normal.

It is not fully clear what exactly was meant with "inexplicably unreasonable" as
this does not give any hint about what was actually observed. Also, what occurs
after you power cycle the board depends on the way you updated SJA1110 firmware,
it can start either 1G or the default 2.5G if you did not program the updates
FW into the Flash. If you wish more suggestions in regards to the described
problem, please provide more details on how exactly is was determined that
it is related to the data rate modifications you have done and what are the
actually observed symptoms.

If I start with the A core, I can start after the first power-on, but I have to power off for a long time when I start the second time.Or Unplug the DC terminal and plug it in again,it can still start.
