Dear Sir,

I found a problem when trying to program the Flash memory. I am using Reva V2.0 with STR750F module (Ride version in other post of mine).

Using RFlasher, I load a sample .bin ("1234567890" in ASCII codes) at address 0x2000_0000. I can see the ten bytes loaded in the RFlasher window, I can program them, I can read back them, all is ok.

When I try to load the same sample .bin, but at address 0x200c_0000 (the BANK 1 FLASH, 16k), the RFlasher window remains blank, i.e. FF FF FF FF FF FF FF FF FF FF. No programming happens thereafter, and if I read back the data, I read only FF.

So I suppose there is a bug in RFlasher.

In addition, I tried to use IAP (In Application Programming) to write FLASH while executing from RAM: I can erase/write/read all of the FLASH at BANK 0, but, again, ERASING/WRITING/READING at BANK 1 doesn't work. This could be a mask problem of the STR752FV2 (engineering sample), or it may be a problem of RLink?

I tried with n.2 Rlink Pro and with n.2 STR750F modules, with the same result.

Instead, using an STR711F module, I can load the same .bin at any address, included the BANK1 FLASH, and I can program it without problem (in this case the address is 0x400c_0000).

Microcontroller code:

STR750FV2T6
Z
22 024 VG
MLT 22 630
ST ARM

Please answer.

Regards

Romano
