However, considering only 32KB for iRam_0_seg and Other SDK libaries aldready takes around 27KBytes of iRam_0_seg and leave user codes only less than 5KBytes of Non-ICACHE iRam1_0_seg barely no. Why Espressif SDK still continues to consume iRam1_0_Seg further?
We tried to place the text codes of libphy.a into ICACHE iRom0 seg, but brings about failures of exceptipn 0 IllegalInstructionCause. All code that could be placed into ICACHE iRom0 of the SDK libaries are placed by our project, but still has no additional iRam1_0_seg for new version of libphy.a. Then How?
