"do not use fast download"

[yangliang]

I made a board use in MPC8313,in the CW Release v8.8.3 patch, i find if not check  "do not use fast download" in USBTAP edit connection,my board can't use the flash programmer,in the DDR memory the flash driver can't download right ,so can't to write to flash.but if i check  "do not use fast download" ,it can use the flash programmer and the code download to DDR right. So i want to know what the different between check and not .fast download do something? But in 8313RDB board it can work both check and not check this?

According to the Power Architecture Targeting manual (located in the Help folder of the CodeWarrior installation), the Working with the Debugger chapter,  there is a download mechanism optimized for speed, and another that uses the regular (slow) download mechanism. The documentation does not describe the difference between the two download mechanisms. As you have discovered, the fast download does not work for all hardware configurations, in which case you fall back to using the slow download. (You did this by checking the Do not use fast download option.). Use what works, and stick to the slow download.

Can confirm that the MPC8313 and CW v8.8.3 Build 90619 still has this issue. Thankfully found this forum post, many thanks yang.

I verified CodeWarrior 8.8 applied Patch 8.8.5(including all previous patches) with MPC8313RDB target board, both "fast download" and "non fast download" work well.

Have a great day,
