AM3358: U-Boot booting issue

J E

Part Number: AM3358

I would like to ask support about an issue I have using the AM3358BZCZ100 on a custom board. 2313.schematic.pdf

have compiled the u-boot using u-boot-2018.01 from the TI EVM SDK.
I used the compiler that comes with the SDK.

I configured the board to be a board_is_bone_lt() and prevent reading the eeprom from the link below:
e2e.ti.com/.../876780

I use an SD card on the MMC0 port on the CPU.
U-Boot is giving me the following output to my computer, and then it hangs. After a minute it retries and give the same output again.

Trying to boot from MMC1
*** Warning - bad CRC, using default environment

Do I need to configure the default boot MMC0 somewhere?

Hello J,

The EEPROM skip method you have used applies to the old SDK versions where the EEPROM detection and reading has done in <SDK>/board-support/u-boot-<version>/board/ti/am335x/board.c file and it is no more convenient to use it with the latest Processor SDK where the EEPROM reading is done by a common <Processor SDK>/board-support/u-boot-<version>/board/ti/common/board_detect.c file.

You can refer to this patch and use that method on old SDK and this on new Processor SDK versions.

The hang you observe on that point may be caused by a wrong PINMUX settings in the board's device tree or <Processor SDK>/board-support/u-boot-<version>/board/ti/am335x/mux.c file. Please, see this thread for more details. You can add #define DEBUG line in <Processor SDK>/board-support/u-boot-<version>/include/configs/am335x_evm.h file to make the output more verbose and see where exactly it hangs. If you met the `.rodata' will not fit in region `.sram' error while compiling MLO with defined DEBUG flag, please refer to this post.

Best regards,
Kemal

Hello Kemal,

Thanks a lot for your reply. I have followed all the steps.

I still seem to have the same issue. Perhaps regarding the MMC1? I don't want the AM3358 to boot from MMC1 but MMC0 anyways.
Here is my current pinmux, after changing from the post you mentioned. Below that the output from u-boot with the DEBUG defined.

"Trying to boot from MMC1" message means that the board tries to boot from mmc0, if it tries to boot from mmc1 the printed message will be "Trying to boot from MMC2".

Continuously reading the u-boot.img and never be able to load it may indicate an issue with the SD card signal levels or most probably the read bytes gets lost in your RAM memory because of improper DDR timings. You will need to tune the DDR timings, if you have not done that yet. You can check this, this and this thread for more details.

Thanks.

For the DDR ratio sheet, I see the following registers as output:

DATAx_PHY_RD DQS_SLAVE_RATIO	40
DATAx_PHY_FIFO_WE_SLAVE_RATIO	40
DATAx_PHY_WR DQS_SLAVE_RATIO	0
DATAx_PHY_WR_DATA_SLAVE_RATIO	40
CMDx_PHY_CTRL_SLAVE_RATIO	80

Where in u-boot they should be filled in? As I see these variables for my DDR2 memory in ddr_defs.h but the naming is completely different. Or am I looking at the wrong spot.

I matched them up with color coding above to help. The "RATIO" one was tricky! Also of note, DDR3 configs define .datawdsratio0 in the board.c structures. I see it isn't even listed in the DDR2 structures, presumably since it's always 0, i.e. that's where ordinarily you would assign the WR DQS_SLAVE_RATIO value.

On a related note, I strongly recommend that after your board is booted you do the following:

Connect with JTAG.
Verify MMU is Off in bottom line of CCS (otherwise that can mess with addresses).
Open memory window to address 0x80000000.
Refresh the window a bunch of times to see if anything turns red, which would indicate data is changing which is bad.
Poke a data value into memory somewhere. Refresh it a bunch of times and see if it sticks.

The above test is just very rudimentary. It is an easy way of finding a severely broken memory interface. On the other hand, if everything is good that's a good sign, but doesn't necessarily mean your interface is perfect.

Sorry, I have one more question which is more hardware related. I was not able to find it in the datasheet.

My DDR2 module is not using the DDR_A14 and DDR_A15 pins, which means they are not connected to the AM3358.
Do I need to directly connect these 2 pins to GND at the AM3358 side? Or can I leave them unconnected.

Thank you.

Leave them unconnected.
