Other Parts Discussed in Thread: TPS62362
Tool/software: Linux
Hi,
a customer is starting a project based on Linux on AM437x SoC. They have problems when starting Linux on TMDSIDK437X.
They loaded according to the instructions of http://processors.wiki.ti.com/index.php/Processor_SDK_Linux_create_SD_card_script the „pre-built images“ onto the SD-Card which came with the TMDSIDK437X. When starting TMDSIDK437X then UART provides the below (those are not there when removing the SD card). It only occurs with Rev 1.4 A, not with Rev 1.3 A. Same SD-Card and same data was used for both.
