Re: CRC on 1446

Thanks Wilfrido,

i noticed also that many DSP registers got undefined, as reported by the host mcu compiler,

when i turn on the CRC check so i use the newly generated *.h files.

If you want, i can be more specific.

Regarding the zero filling, i understood you fill the program memory in 4092 zero-valued bytes chunks,

moving the address of the next block by 682 bytes, that is the initial address shifted by 4092 / 6 instructions

(because each instruction is 6 bytes long), until the whole program area is filled up with zeros.

So i'm asking, instead of zeroing the program memory then downoading the program,

may i download the whole program, then fill up the remaining memory with zeros?

I could do this without having to declare zero filled arrays, just simply making a loop and sending

a sequence of zeros into the spi-communication routine till program memory end.

Many thanks.

Tom

EDITED ON May 8th

Here are the registers that get undefined when i turn on CRC check.

Please give a word on this and if i can zero-fill the remaining program ram

programmatically, instead of defining a zero-filled array.

(re-edit) I see that the registers are not undefined, rather the Rx_REGISTER_NAME

identifier number (R4, R3 ..) become different if i compile with or without CRC

check.

This maybe because they are enumerated serially and with crc check there

are 8+ programming steps so only the first ones (those before program ram data)

are equal.

Many thanks.
