I had my avenger96 sitting on my desk for a few weeks, no if I try to boot it, I am getting the following (pre?) u-boot panic:
NOTICE: CPU: STM32MP157AAC Rev.B NOTICE: Model: Arrow Electronics STM32MP157A Avenger96 board INFO: Reset reason (0x15): INFO: Power-on Reset (rst_por) INFO: Using SDMMC INFO: Instance 1 INFO: Boot used partition fsbl1 INFO: Product_below_2v5=1: HSLVEN update is INFO: destructive, no update as VDD>2.7V NOTICE: BL2: v2.0(debug): NOTICE: BL2: Built : 13:13:37, Oct 2 2018 INFO: BL2: Doing platform setup INFO: PMIC version = 0x10 INFO: RAM: DDR3-1066/888 bin G 2x4Gb 533MHz v1.41 ERROR: DDR addr bus test: can't access memory @ 0xc0000004 PANIC at PC : 0x2ffdf9d9 Exception mode=0x00000016 at: 0x2ffda000
Since nothing on the firmware side changed, I worry this is hardware. I need help in understanding what actually failed. I am guessing Memory failure perhaps?
I am using this sdcard image: https://releases.linaro.org/96boards/avenger96/19.10/
I have tried multiple sdcards so its not that.
I tried with a known good upstream uboot build that i had flashed on the av96’s spi flash, that has stopped responding as well, nothing on the uart at all.
