i have old WisNode board with STM32L151CB (not STM32L151CB-A)
Flash size 128K but RAM only 16K (from 20000000 to 20004000)
So RUI_RAK811_V184.108.40.206.H.bin can’t start because stack pointer set to 20008000.
Also SysTick timer not disabled on jump from bootloader to application.
Can you publish source codes so i can change for my strange RAK811 ?
Thanks in advance
P.S. If i change 20008000 to 20004000 firmware works.
