hi:
I use f28020 to run BLDC program , program migrate from controlsuite BLDC-Sensor . original program use f28035 mcu.
we know f28020 is 3k ram place . in cmd, it separate three space , RAMM0 ,RAMM1, RAML0. 1K+1K+1K=3K;
but now :
warning #16002-D: build attribute vendor section TI missing in "../IQmath.lib<IQmathTables.obj>": compatibility cannot be determined
"../F2802x_generic_flash.cmd", line 112: error #10099-D: program will not fit into available memory. run placement with alignment/blocking fails for section "ramfuncs" size 0x44b page 0. Available memory ranges:

error #10010: errors encountered during linking; "F28020BLDC_AC.out" not built
in cmd:

my program need 0x44b , but RAMM0 is 0x400. what can i do now .?
best regard !
