| Post subject: | New LIMA devices not booting |
Hello, We have our own developed carrier board which includes a LIMA, however the LIMA does not boot. When monitoring the UART upon toggling the RESETN we can see the bootloader start, and then it hangs after displaying the following: """"""""""""""""""""""""""""""""""""""""""""""""""""""""""""" U-Boot 1.1.4-gefc36cf5 (May 25 2018 - 13:19:10) ================================ Caraboot v2.7 (QCA9531) U-boot http://www.8devices.com/ ------------------------------------------ DRAM: 4 MB | """"""""""""""""""""""""""""""""""""""""""""""""""""""""""""" Do you have any suggestions to what may be causing this? Thanks Joe |

Make sure GPIO_10/UART TX isn't pulled up on your carrier board. As it's used for DRAM type (DDR1/2) detection, it has to be pulled down during bootstrap stage (first ~5 ms). |
