Hi,
do you have use other program show board log?
if you have use other program show message, please help me close.
and check setup.py UART_COM_ID = 3 # COM5 is it right or not.
It worked. Thank you for your support
Hi Jennifer Lin,
Can i ask you that, where can i get 2 files fw_ncpu.bin and fw_scpu.bin? And "generated by Keil", what does it means?
i took it from \host_lib_v0.9.1\host_lib\app_binaries\KL520\tiny_yolo_v3, but when flash program into KL520, it just show little codes and nothing display on screen.
Hi,
please took from kl520_sdk_v1.4.0.1 below pic, fw_ncpu.bin is ncpu folder, fw_scpu.bin is scpu folder and generated by Keil.
Sorry, I still can't find it. Is it available or do i have to build it by myself?
HI,
please refer https://www2.keil.com/mdk5/docs and if you download keil C requires certification to use.
I see. I have another question, please help. Following this http://doc.kneron.com/docs/#520_1.4.0.0/getting_start/#4-run-the-default-application-tiny-yolo-v3. I type command ~/host_lib/build/bin$ ./kl520_isi_async_parallel_yolo:
I connected my computer with KL520 via UART0 port. Did i miss anything?
Best regards.
1.do you have update kl520_sdk_v1.4.0.1 model and fw?
2.do you have reset your board?
thanks
1.I have not. How to update? Is it same way flash programming?
I want to test step 5 of the document (Run ota ...) but as you can see that "add device failed" (step 4 like that too). I connected via UART0 port, Did I connect correctly?
If we need model and fw from kl520_sdk_v1.4.0.1 to update, what does the model and fw from host_lib_v0.9.1 means? can use it or not?
2.I tried to press reset button, cut off and turn on power, but it still doesn't work.
Thanks
Thank you so much!
1. if you are 96board please reference 10. Flash programming, or 10.3.4 Flash Chip Programming (FW + DATA) and 10.4. Program Flash via JTAG/SWD Interface
2. yes
4. you are 96board, so please use kl520_sdk_v1.4.0.1, we host_lib_v0.9.1 is for USB dongle. thanks
