Hi,
I have a MIMRT1020-EVK board and use Keil µVision IDE.
I'm making large rom size program like here:
Program Size: Code=26800 RO-data=145632 RW-data=1888 ZI-data=2520
Then, I changed in scr file:
#define m_text_start 0x00000400
#define m_text_size 0x00400000
But I can't load program on µVision.
It stopped loading 37% and "Cannot access target"
Please see attached cap.JPG.
What am I missing here?
Kind regards,
Sako
Hello,
Parameter m_text_size of 0x00400000 looks very big.
You may look at Your linker map file to define what addresses are really involved here.
Table 2-1 (System memory map ...) in the i.MX RT1020 Reference Manual
shows available memory. For example only 256KB of ITCM is available.
Also, look at app note “Using the i.MX RT FlexRAM”

Have a great day,
Yuri
