Hi @13824125580, >as i know, the Nuttx SMP it not stable at present. It's much stable than before but I need more work to fix some problems. >It seem s the K210 default configuration not support SMP @btashton You can use maix-bit:smp configuration with QEMU as well as a real board. However, please note that OpenOCD with maix-bit is sometimes unstable. >As my experience with qemu , on SMP scenario,some timing related issue cant be reproduced on Qemu. Exactly. That's why I've started to use the sabre-6quad board recently to fix L1 d-cache issue. With QEMU, we can test some simple use cases such as ostest, but we can not test cache coherency issues. Also, real use-cases (e.g. W-Fi audio streaming and so on) are much more complicated, because many drivers (e.g. SPI, DMA, I2S, ...) are involved. To test such use-cases, I've been using Sony Spresense board. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
