AM3352: MMC2 configuration issue

Part Number: AM3352
Other Parts Discussed in Thread: WL1837, WL1835, WL1837MOD
Hi Experts,
A customer has been developing AM3352 with WL1837MODGIM0CR.
They are testing the system as follows:
PC(RealTime Tuning Tool)COM1―UART5(AM3352)－MMC2(AM3352)－WIFI(WL1837)
With this system, they have a problem that the MMC2 (AM3352) is not recognized as a SDIO.
They would like to know which files they have to modify.
I have received these files below from the customer.

am33xx.dtsi
am335x-evm.dts
.config（tisdk_am335x-evm_defconfig）
and log file.

I could send the files locally if you need. So please let me know.
Thank you so much in advance for your skillful support.

Best regards,
Hitoshi

There is actually a readily available design called BeagleBoneBlack Wireless that has an WL1835 WiFi module connected to MMC2 of an AM335x device which seems pretty similar to the system you are describing here.
https://beagleboard.org/black-wireless
Hardware Design Files
https://github.com/beagleboard/beaglebone-black-wireless
Kernel 4.19 Device Tree File (includes description of WL1835 connected to MMC2)
https://github.com/beagleboard/linux/blob/4.19/arch/arm/boot/dts/am335x-boneblack-wireless.dts
And this is the associated "defconfig" for building the Kernel for BeagleBoneBlacks, including the wireless version
https://github.com/beagleboard/linux/blob/4.19/arch/arm/configs/bb.org_defconfig
I suggest you start from this Kernel snapshot (DTS, config) to see if you can establish a known-good reference point, and then investigate why the customer system does not work.

Hi Andreas,

Thank you for your quick reply.
Let me dispatch the suggestion to the customer.
Will keep you updated.

Hi Andreas,

Thank you for the BeagleBoneBlack board use case examples.
According to the DTS configuration, the customer thinks their program seems correct.
There might be any other portion has issues.

For further investigation, could you please help these questions as follows:

1.MMC clock setting
Is it set in the file /include/ "am33xx-clocks.dtsi which is included by DTS?

2.MMC register look up
The look up function was developed and checked the address.
The addresses for UART and RTC registers were able to be read correctly.
However, the address for MMC was not able to be read and it is Segmentation fault.
If there are any points where must be fixed, please let us know.

( readl_relaxed( ioremap( addr, REG_DRV_REMAP_SIZE ) ) )
　( readw_relaxed( ioremap( addr, REG_DRV_REMAP_SIZE ) ) )
（UART register look up: OK）
root@am335x-evm:/# reg-read32 44e09000
000000e1
（MMC register look up : NG）
Segmentation fault
root@am335x-evm:/# reg-read32 481d8000
[ 578.577923] Unhandled fault: external abort on non-linefetch (0x1028) at 0xfa1d8000 [ 578.585995] Internal error: : 1028 [#2] SMP ARM

3. Please let us know the version of the SDK and the protocol stack when TI evaluated the WiFi/BT operation with AM3352 and WL1837MOD?
Thank you in advance for your kind looking into the issue.

It really depends on the entire DTS include and overlay hierarchy, starting with the top-level dts file. Sometimes it can be confusing to decipher the actual final configuration for a given peripheral but one thing you can do is to use the device-tree compiler (dtc) to reverse-compile a binary device tree blob file back into source code. This way you see the final file as it will get consumed by Kernel and which settings will be active.
For example to see the final device tree config used for the Kernel on a current 4.19 Kernel for the wireless beaglebone black you can do this

2.MMC register look up
The look up function was developed and checked the address.
The addresses for UART and RTC registers were able to be read correctly.
However, the address for MMC was not able to be read and it is Segmentation fault.
Looks like it could be that the clocks may not be turned on for that MMC module (or it is held in reset). Make sure the device is enabled via device tree. One thing for this to work is the node needs to have a status = "okay" entry, as shown in the above example from BBB wireless. Then, double-check the addresses you are trying to read from that those are valid MMC module addresses.

3. Please let us know the version of the SDK and the protocol stack when TI evaluated the WiFi/BT operation with AM3352 and WL1837MOD?
I don't think we actively test this combination with the official SDK hence I was pointing to the community project to serve as a known-good starting point.
If the issues persist also feel free to share a full(!) boot log for inspection.

Hi Andreas,

Finally, wlan0 creation was confirmed and it works on MMC2 after “calibrator” command was issued from UART in Karnel.
Thank you so much for your kind support on this issue.

Will keep you informed if any further issue occurs with creating another new thread.

Best regards,
Hitoshi

Sugawara-san,
thanks for closing the loop here and reporting back on how the issue was fixed.
