Hi Expert:
On our customized TDA4 board, after the SW8 and SW9 pins are pulled into the eMMC startup mode, the serial terminal does not output any information. The relevant details are as follows:
1. Dial code configuration:
SW8[1-8] = 1000 0000
SW9[1-8] = 0100 0000
2. SDKs:
ti-processor-sdk-linux-j7-evm-08_00_00_08
ti-processor-sdk-rtos-j721e-evm-08_00_00_12
3. Other introduction:
The DIP circuit of SW8 and SW9 is the same as that of TDA4VM.
eMMC can read, write and burn images normally.
Please help us analyze and locate the cause of the problem, and guide us to solve the problem correctly.
Thank you for your support and look forward to your reply.
