AM2434: AM2434 HS-FS Device Questions.

AndreTseng

Part Number: AM2434
Other Parts Discussed in Thread: UNIFLASH

Hi expert,

My customer just got HS-FS device. They are trying to program it on their board. They are using following configuration file to program it.

Basically, just replace prebuilt GP images to prebuilt HS-FS images for flash writer, sbl_ospi.

The hs-fs image for hello world is recompiled from CCS and generate automatically by default makefile_ccs_bootimage_gen.

ospi_sbl_app.cfg

You can see they can program device successfully. However, reboot device, the device doesn't work and they can't get anything output from UART.

The same situation when they change to program sbl_null. Device can be programmed but boot fail.

Field FAE doesn't have HS-FS EVM, can you please help? Anything missing in their steps?

Regards

Andre

Hi AndreTseng,

As per the logs, it seems like the device is indeed HS-FS device because the SBL_UART_UNIFLASH seem to work perfectly fine. Let's try to debug this with SBL-NULL -

Can the customer try to connect to R5_0 CPU and check where the program counter is ? Is the boot mode correctly selected as xSPI to see this result right ?

Aakash,

There is no output from sbl_null. They can't connect JTAG. Can you please help to check anything different in between RBL and SBL? Any pin that SBL has pull up, but RBL doesn't?

Regards

Andre

Hi AndreTseng,

Is this a custom EVM or a TI-EVM ?

Aakash,

It's custom board. If images and processes they are using to program FLASH is correct, we will ask them review HW first. And please provide if there is pad setting difference between RBL and SBL, that will help.

Hi AndreTseng,

I will check the HW from the experts. Another approach that can be done is using uart_bootloader.py / UART BOOT MODE.

More details - https://software-dl.ti.com/mcu-plus-sdk/esd/AM243X/latest/exports/docs/api_guide_am243x/BOOTFLOW_GUIDE.html#autotoc_md302
https://software-dl.ti.com/mcu-plus-sdk/esd/AM243X/latest/exports/docs/api_guide_am243x/TOOLS_BOOT.html#UART_BOOTLOADER_PYTHON_SCRIPT

This will rule out if there is a problem with flash HW or not.

Also my suggestion is to first start with a simple Hello World and then try the OSPI_IO example to confirm if the HW is functional or not -
https://software-dl.ti.com/mcu-plus-sdk/esd/AM243X/latest/exports/docs/api_guide_am243x/EXAMPLES_DRIVERS_OSPI_FLASH_IO.html

Hope it helps with more information.

Best Regards,
Aakash

Customer use the same OSPI flash as our EVM.

They can pass OSPI_IO test, and also OSPI_DMA_Transfer test. Please refer to log from these test as.

I don't think their HW has problem.

They also can use uart to flash HS-FS device without any error.

HOWEVER, the device can't boot. There is no message from UART. Any suggestion?

Hi AndreTseng,

Everything seems okay to me. Can we schedule a call to debug this issue ?

Aakash,

Customer confirm this issue happens on both GP & HS-FS device with SDK8.5.

After changing QE bit enable type from "0" to "5" in syscfg, this problem can be solved. Thanks for your help.

Regards

Andre
