how to download the firmware image larger than 1MB #30

Closed flagyan closed 3 months ago

flagyan commented 3 months ago

Hi,

Is there a method to download firmware image larger than 1MB? I have built my library in the firmware and got a 1.5MB .img file. Thanks in advance.

Hi @flagyan,

Firmware image size cannot be larger than 1MB. Does your code include model files? If so, you can put the model file into flash memory.

Hi @stevehuang82,

I have a very big library to implement complex functions and so result in a 1.5M image file. Where is the limitation of 1MB from? Is it from the download function? Then can I use the debugger to flash it directly? Thanks.

stevehuang82 commented 3 months ago

Yes, the limitation is from the download function. I think you can use the debugger to flash it directly. I will confirm that later.

Hi @stevehuang82 ,

I am setting up the debug environment with jlink and get the 'Unspecified error' as #28, do we need any extra setting besides https://github.com/HimaxWiseEyePlus/Seeed_Grove_Vision_AI_Module_V2/blob/main/swd_debugging/README.md? for example, enable the SWD in the image, I see that in the https://github.com/HimaxWiseEyePlus/Seeed_Grove_Vision_AI_Module_V2/blob/main/EPII_CM55M_APP_S/app/scenario_app/allon_sensor_tflm_freertos/allon_sensor_tflm.c, there is code to enable the swd but it is commented out. Thanks a lot.

Hi @stevehuang82,

I can download the image with a cmsis-dap debugger now. Thanks a lot.
