Issue with programming Binaries using Uniflash on AM4377 based platform

Krishna Prasad

Other Parts Discussed in Thread: UNIFLASH, AM4377

Hi All,

We are trying to program the binaries to flash using Ti's Uniflash tool on our custom board, which has AM4377 (Silicon 1.2).

We followed the procedure in the below link
processors.wiki.ti.com/.../Sitara_Uniflash_Flash_Programming_with_U-Boot

Tool:-
We have installed Uniflash 3.4 on Windows 7 Host PC and trying to program the
binaries over Etherner Interface.
Images required for flashing and images to be flashed are generated as mentioned in
the TI wiki.

Setup:-
Direct Ethernet connection made between Host PC and target. Static IP assigned in
Host PC (192.168.2.1 as Network Interface IP and TFTP IP ).
Ethernet Boot settings are made in custom board.

Problem:-
We are not observing any status on UniFlash Status View(Console).
Also We are not getting ‘C’ character in Debug UART console which should come once target board is booted in peripheral boot mode (Searching for HOST)

We checked the opendhcp logs and we found the following observation

“Server is listening on 192.168.2.1 (TFTP Server/Network interface IP). But not
receiving any BOOTP request from target board.”

Please let us know any other setting need to be done on custom board to send BOOTP
request or Ethernet boot setting alone is enough?

Hi,

Current version of Uniflash does not support AM437X devices. See: processors.wiki.ti.com/.../CCS_UniFlash_v3.4_Release_Notes

Hi Biser,

Thanks for your reply.

As per below link, we can use Uniflash for AM437x SOCs
processors.wiki.ti.com/.../Sitara_Uniflash_Quick_Start_Guide

Which Uniflash version supports AM437x ?

Regards,
Krishna

I have asked for clarification from the factory team.

Hi,

I have checked the Trace vector word 1 value when board is powered on in EMAC boot setting and Host PC side Uniflash is running.
I am getting value as 302E which means following bits are set.

Bit 1- Entered main function
Bit 2 - Running after the cold reset
Bit 3 - Main booting routine entered
Bit 5 - Peripheral booting started
Bit 12 -Device initialized
Bit13 - Searching for HOST (Bootp message in USB_CL/EMAC , ‘C’
character in UART)

But I am not getting any 'C' value on UART and opendhcp also not receiving any BOOTP request.

Regards,
Krishna

What is your processor silicon revision? Peripheral boot is not supported on Rev. 1.1 devices. See AM437X Errata Rev. B Advisory 10.

Silicon version is 1.2

Krishna,

Can you please try adding the below two lines to your opendhcp.ini file inside your Uniflash install? The entries for the other processors should be near the top.

AM43xx ROM=u-boot-spl-restore.bin
AM43xx U-B=u-boot-restore.img

I'm sorry, I can't validate this just now, but these seetings, once applied and the server is restarted, should allow you to start seeing the BOOTP requests. I have validated Uniflash works with AM437x rev. 1.2 Si.

Hi RonB,

Thanks for your reply,

I have added this lines in opendhcp.ini file. But Still not not seeing BOOTP request from target board

Regards,

Krishna

Krishna,

Can you use wireshark on the PC to see if the request is coming in from the board?

0 Krishna Prasad over 9 years ago in reply to RonB

Hi RonB,

I have analysed the network packets using wireshark and I did not see any request from board.

Following are my observation.
1. On Board bootup Tracing vector word 1 value is 0x0000302E (Entered main function,Running after the cold reset,Main booting routine entered, Peripheral booting started,Device initialized, Searching for HOST) and after some time word 1 values is 0x0001B06E ( Host not found and Peripheral booting failed bits are 1 in addition to previous set values). But Host PC side Uniflash is running, opendhcp server on listening mode. Direct ethernet connection between Host PC and board.
2. For EMAC boot SYSBOOT 4-0 are set to 11100 , SYSBOOT 5 and SYSBOOT 18 set to 1 respectively.

Let me know If I am missing anything

Regards.
Krishna
