When boath task run together then started get

LPC espresso version 7.3,

I used heap_3 as it is not thread safe and gave me pretty much same error. LPC1769 have huge RAM in different banks

Q1. How to configure the linker script to use  stack and global variable in 1 bank and heap in different bank?
