Ticket Name: Compiler/TDA2EVM5777: The kernel is stucked or got a panic.

Query Text:
Part Number: TDA2EVM5777 Other Parts Discussed in Thread: DRA742, DRA752 Tool/software: TI C/C++ Compiler Hi, I'm trying to boot custom board which is based on TDA2x EVM board. Sometimes, it goes to mount root file system but seems like wait infinitely some task. (it doesn't show root login prompt) And it often shows kernel panic messages. I attached my kernel log.

Responses:
Hi Yoo, we are looking at this and will reply here soon. Regards, Yordan

Hi If the failures are random during the boot process, have you ensured that memory part is stable on your evm. Memory instability can often lead to such random crashes - can you check by running memtester or similar Also, include additional information on the SW(SDK) version that you are using and changes carried out at your end

Hi Sriram, Is there any way to check memory instability when i can't enter into root prompt? That error occurs in the process of kernel start or systemd. I'm using vision SDK 3.7 version and only changed the power of mmc1 in dts from evm_3v3_sd to eve_3v3_sw. In addition, when i execute bdinfo in u-boot, 2 part of DRAM bank were shown but the size of second DRAM bank was shown as 0. Is this normal? If not, could you let me know how can i fix it? Thanks and Regards, Yoo

hi For the memory stability, hope you have reviewed the schematics and taken care of recommendations from TI You can check if memory is stable by running memtester utility. Also, would be good if you can clarify if the issue is seen on multiple boards or only on few boards. AFAIK, there is no means to auto-detect the amount of memory installed in a system. In case of TI EVM, the information is obtained by reading programmed information from EEPROM on the EVM. The information is then used to patch through the amount of memory passed to the Linux kernel - the device entries for amount of memory is modified from uboot

HI Can you confirm if the issue has been resolved If the issue is not seen anymore will mark the thread as closed and we can reopen the thread if needed at a later point of time
