ValueError: [MAIXPY]kpu: load_flash error:2006, ERR_NO_MEM: memory not enough

[KuoEuran]

Hi, I am using the Maxiduino to load my kmodel which is 5.6MB. I follow https://en.bbs.sipeed.com/t/topic/1811 to make my kmodel be big-edian, and I use the command task = kpu.load_flash(0x174000, 1, 1, 60000000) Howerver, it appears the error. Can anyone give me some advice to solve this error, tks.
