TDA4VM: TDA4 uart boot issue

Hi,

https://e2e.ti.com/support/processors/f/791/t/1028163

The above reduces the DDR speed. Can you try the above & let me know if you are able to boot on the failing board?

You could directly try with this binaries set: e2e.ti.com/.../sdk8_2D00_0_2D00_3733_2D00_ddr.zip

If it unblocks you then please click on verify answer.

Hi,

  I tried directly with the binaries tiboot3.bin in the link above, I'm still not able to boot on the failing board, the error log is the same as the picture above, the tiboot3.bin can be uploaded through xmodem successfully but the sysfw.itb can't be uploaded.

Hi Billy,

Can you try any other boot mode on the failing board? SD boot?

Hi Keerthy,

  It's our custom board which don't support SD boot, only support uart boot and eMMC boot, we are not able to boot from eMMC because we may run out of the life of eMMC, so we need to boot through uart.

Hi Billy,

So how many boards are failing like this?
Is the failing board & passing board same version of your custom board or different version?
Can you replace the failing sample on the working board just to rule out any board related issue?

Hi ,

   As to the sx of xmodem can support only one file transfer at a moment  ,could yo please combine the tiboot3.bin and sysfw.itb together as one file by TI's script? 

Hi Keerthy,

  There is only one board which has the issue, it's the same version as other normal board which can successfully boot from uart, if there is no more intuitive reason we will try to replace the failing sample, but we just want to narrow the scope of the problem, the TDA4 chip, DDR or eMMC, which may cause the above error log?

Hi Billy, 

  There are  2 suggestion to you  1 using TRACE32  download the image  if the Jtag port is available.    2  Maybe you can capture the R5F and DMSC log by ccs.
