I notice that microTVM can directly support mimxrt1050_evk, but I'm working on one mimxrt1060_evk. I'm wondering whether microTVM can also run on 1060_evk, because these two boards are quite similar, they both belong to rt10xx and cortex-m7 boards, they are both supported by zephyr.
So far, I have made some try based on the guide https://tvm.apache.org/docs/how_to/work_with_microtvm/micro_tvmc.html, but there are still some problems. My enviroment: ubuntu 20.04 (vmware) tvm 0.9 (commit 7e376e2599b6422bb1562bdf1823413276914d5d), set(USE_MICRO ON) llvm-10 zephyr 2.7.0 (installed diretly instead of ReferenceVM), sdk 0.14.2 JLink 7.66c What I have tried: 1. compile > python -m tvm.driver.tvmc compile magic_wand.tflite --target='c -keys=cpu > -link-params=0 -mcpu=cortex-m7 -model=imxrt10xx' --runtime=crt > --runtime-crt-system-lib 1 --executor='graph' > --executor-graph-link-params 0 --output model.tar --output-format mlf > --pass-config tir.disable_vectorize=1 --disabled-pass=AlterOpLayout output: conv2d NHWC layout is not optimized for x86 with autotvm. conv2d NHWC layout is not optimized for x86 with autotvm. One or more operators have not been tuned. Please tune your model for better performance. Use DEBUG logging level to see more details. 2. flash project edit board.json in build/microtvm_template_projects/zephyr/boards.json add: > "mimxrt1060_evk": { > "board": "mimxrt1060_evk", > "model": "imxrt10xx", > "is_qemu": false, > "fpu": true, > "vid_hex": "1366", > "pid_hex": "0105" > }, > python -m tvm.driver.tvmc micro create project model.tar zephyr > --project-option project_type=host_driven zephyr_board=mimxrt1060_evk > python -m tvm.driver.tvmc micro build project zephyr > --project-option zephyr_board=mimxrt1060_evk > python -m tvm.driver.tvmc micro flash project zephyr --project-option > zephyr_board=mimxrt1060_evk **No explicit error** 3. run > python -m tvm.driver.tvmc run \ > --device micro \ > project \ > --project-option zephyr_board=mimxrt1060_evk \ > --fill-mode ones \ > --print-top 4 `Error: Could not open a session with the micro target.` And there are some output in serial, but it also looks not very good.  Can anyone help me, thanks! --- [Visit Topic](https://discuss.tvm.apache.org/t/how-to-use-microtvm-with-mimxrt1060-evk/12993/1) to respond.
