I test sja1110 on S32GRDB2 , I have set SW12 to 1-1, sja1110 is OK when boot S32GRDB2, log as below:

why sja1110.ko cannot be insert at second time?

Re: modprobe sja1110 fail

Daniel-Aguirre — Tue, 21 Mar 2023 20:52:18 GMT

Hi,

Could you please let us know with which BSP you are working with?

The situation could be related to the SJA1110 not being set a second time to receive the new FW, have you tried resetting the SJA prior to sending the new FW?. Even though your SW12 configuration is as expected for the first boot, the second time you try to send the configuration the SJA is not waiting for any SW (it is running the application) for which the problem may be caused.

Please, let us know.

Could you please let us know with which BSP you are working with?
-----BSP 30.0

have you tried resetting the SJA prior to sending the new FW?
-------yes, but it still have the error log

I got the sja1110_switch.bin and sja1110_uc.bin from goldvip-1.3.0

In between the rmmod command and the modprobe command we have issued a RESET to the SJA1110 by grounding the R1211 for a short period, as shown below:

After doing this, we issue the modprobe command and the software was successfully loaded to the SJA1110.

Please, let us know.

Re: modprobe sja1110 fail

shanlan123 — Thu, 23 Mar 2023 10:45:30 GMT

Thank you. After grounding R1211, I can load sja1110.ko second time successfully.
I previously reset sja1110 by command "echo a > /sys/devices/platform/402d0000.spi/spi_master/spi5/spi5.1/switch-configuration/switch_reset", but it seems failed. Do you have any ways to reset sja1110 through software? Instead of manually grounding R1211.
I saw that your log printed "Could not get GPIO from device tree". I guess sja1110.ko also tried to reset sja1110, but it also failed.

Daniel-Aguirre — Thu, 23 Mar 2023 22:55:32 GMT

Hi,

There is a GPIO provided as "SJA_RST_N" which should provide the functionality you are looking for. Below will be an image of the schematic signal:

It should be able to do the trick. It is connected to a Schmidt trigger and an AND gate which its output is connected to the same node that we grounded before.

Please, let us know.

Re: modprobe sja1110 fail

shanlan123 — Mon, 27 Mar 2023 08:44:50 GMT

Thank you, but how to configure the GPIO "SJA_RST_N"?

I saw "SJA_RST_N" by command "gpioinfo gpiochip0", and then I tried to configure it by command "gpioset 0 24=0", but failed, it print "Device Busy".

I also tried to configure it by command "echo 345 > /sys/class/gpio/export", but still failed, also print "Device Busy".(gpiochip0 base is 321, "SJA_RST_N" is in line 24, 321+24=345)

The above operations are all performed in Linux BSP33.0.

I would be very happy if you could teach me how to configure it.

Re: modprobe sja1110 fail

Daniel-Aguirre — Mon, 27 Mar 2023 21:08:18 GMT

Hi,

We have tested the below commands to toggle the SJA_RST_N and we can reproduce the successful outcome.

root@s32g274ardb2:~# echo 24 > /sys/class/gpio/export
root@s32g274ardb2:~# echo out > /sys/class/gpio/gpio24/direction
root@s32g274ardb2:~# echo 0 > /sys/class/gpio/gpio24/value
root@s32g274ardb2:~# echo 1 > /sys/class/gpio/gpio24/value

These were executed in between the rmmod command and the modprobe.

Please, let us know.

Re: modprobe sja1110 fail

shanlan123 — Tue, 28 Mar 2023 03:25:31 GMT

Hi Daniel, Thank you very much at first.

Which BSP you are working with?
I successfully execute your commands on BSP30.0, but failed on BSP33.0. Is there any difference between BSP30.0 and BSP33.0 about the gpio numbers?

Re: modprobe sja1110 fail

Daniel-Aguirre — Tue, 28 Mar 2023 18:10:22 GMT

Hi,

That is correct, it seems the commands we provided before is known as "Legacy GPIO Interfaces", which is supported on BSP30.0.

As for BSP33.0, libgpiod library is provided for this same purpose. More of it is explained on Chapter 20 of the Linux BSP33.0 User Manual for S32G2 Platforms.

Please, let us know.

Re: modprobe sja1110 fail

shanlan123 — Wed, 29 Mar 2023 11:03:49 GMT

I have read Chapter 20 of the Linux BSP33.0 User Manual for S32G2 Platforms, and then I did the following:
I tried to configure GPIO "SJA_RST_N" by command "gpioset 0 24=0", but failed, it print "Device Busy".(in BSP33.0)
I also write a demo with libgpiod.so to configure GPIO "SJA_RST_N", but still failed, it print "Device Busy".(in BSP33.0)

Can you configure GPIO "SJA_RST_N" in BSP33.0? If you can, please tell me how to do it.

Re: modprobe sja1110 fail

Daniel-Aguirre — Wed, 29 Mar 2023 22:11:35 GMT

Hi,

It seems that this specific pin (and others) are being used by other applications, hence the resource is not available. An image showing that gpio24 is "used":

Giving to understand that another process is using this resource. This process should be related to SJA1110 functionality.

Please, let us know.
