M5Stack FIRE, faild to init PSRAM



  • M5Stack FIRE has a PSRAM, but it cannot read the PSRAM's device ID, and external memory test fail with numerous errors.
    Why?

    This is boot log when I try to boot micropython, PSRAM version.

    I ordered on Aliexpress 2 days ago, from Wavgat.

    Is their stock likely to be faulty? They did not answer when asked and sent it anyway.

    If faulty, is the solution to replace the PSRAM?

    I'm using an earlier M5Sstack model with PSRAM and it works without any issue.

    If you can build the firmware, you could build with VERBOSE LOG bootloader option to get more information about the PSRAM detection and the initialization failure reason.



  • Hi,

    I have the same issue. I bought M5Stack FIRE in the Aliexpress Store and I get the same boot message..."Failed to init external RAM"

    I sent a message to the M5stack devs through Aliexpress but no reply. :(

    No PSRAM for me I guess... :(

    @lelehel Hi My Friend, did you order it from our official store ? Please kindly send me an email attached your order# and screen shot of the error. I'll help to ship the replacement asap. My email address: teresa@m5tack.com


  • M5Stack

    @jcsbanks Really sorry about the psram problem. The Wavgat store just one of our distributors. Did they refund or send you replacement ? Maybe you can open a dispute for help. If they cannot do any refund or replace, please contact me via teresa@m5stack.com
