Part Number: TDA2EX17EVM
Tool/software: Linux
Hello experts,
I use tda2ex17 evm board with vision sdk 2.12 (linux version), and found out when set bootargs with parameter "loglevel=0" , IPU2 firmware will failed to load . I dont konw why this problem only happened once(first time test) on tda2ex17 evm board, but it happened very offen when i set bootargs with parameter "quiet" on my customed board(tda2xx + vsdk2.12 linux). when set bootargs with parameter "loglevel=8", IPU2 firmware will success to load.
kernel_loglevel_0.txt is log file of failing to loadipu2 firmware.
kernel_loglevel_8.txt is log file of successing to load ipu2 firmware.
What does the error trace mean, could anyone tell me how to fix this?
