Renesas RA8M1 USB Host, cannot make it work.

[kostbill]

While the USB Device ran out of the box, I cannot make USB Host work.
I am not using the e2studio, just following the normal tinyusb steps.
Is it working normally and I am doing something wrong, or it is not working yet?

I am running the host/cdc_msc_hid example. I am building with the following:
cmake -G Ninja -DBOARD=ra8m1_ek -DLOGGER=rtt -DCMAKE_BUILD_TYPE=Debug -DLOG=3 -DRHPORT_HOST=0 -DRHPORT_HOST_SPEED=OPT_MODE_FULL_SPEED ..

I get the following in the RTT viewer.

00> IS 8000 c800
00> IS 8000 c000
00> [0:] USBH Device Attach
00> Device unplugged while debouncing

Thanks.

Edit: I also didn't forget the jumper configurations for USB Host: J12 1-2 and J15 open.

OK the first idea I had worked, in function bool hcd_port_connect_status(uint8_t rhport), hcd_rusb2.c,
instead of using the ATTCH bit of INTSTS1 register (return rusb->INTSTS1_b.ATTCH ? true : false;)
I used the DTCH bit (return rusb->INTSTS1_b.DTCH ? false : true;).

I have a mouse and it seems to be working, didn't test on other devices yet.

I have no idea why it is not working, and why it works on other RA chips.

You mean the RA8 Host side, correct?
Because the Device side is already working from PR #2906.
Or am I missing something?

oh, I forgot I already added bsp for that board. But its usbhs does not work, did you manage to get usbhs working with ra8 ?

[kostbill]

Yes I did.

I only tested with HID, and the problem, at least for this case, was the one I described above, in the first reply to my question.
The ATTCH and DTCH bit in INSTS1 register, in the function bool hcd_port_connect_status(uint8_t rhport), in file hcd_rusb2.c

last time I tried usbhs does not work with device mode as well. I suspect that is clock isue. Do you have to make any other changes to get it running ? For the DTCH bit, please make an PR (along with any update). I will revise the manual/datasheet later.

[kostbill]

Wait I am sorry I got confused there. No I didn't test with HS, only with FS.
The FS Device is working out of the box.
The FS Host needed the modification I told you about.

I will make a PR later this week. But I don't know if my testing alone is enough to justify a PR.

Can you make a test on your RA8M1 board, as a USBFS Host, without my changed code, and see if it is working?
If it does, then something is wrong with my setup.
If it doesn't work, you can apply my code and if it works, then I can make the PR.

Edit: Please don't forget to set jumper J12 to 1 and 2 and remove the J15 jumper.
