hi ：
We own the TDA development board, very few peripheral devices, electricity after the stop in the boot screen, found that the TF card VQMMC power 3.3 V, according to e2e.ti.com/.../943299, modified code, no other changes, still can't start now, with the two problems
1) Under Boot, cannot press any key to enter the Boot console, directly jump to the kernel to start
2) The kernel is stuck in 5 seconds or so. The log is as follows:
