Rappid Bootloader Erase and program option

prathapvc — Tue, 25 May 2021 11:38:53 GMT

While flashing the application code using .s19 file by selecting "erase and program" option in Rappid Bootloader utility i found that the bootloader erases all 31 blocks of flash memory in MPC5777C

So can you suggest whether we can store the data in EEPROM Data block (0x00030000 - 0x0003FFFF) or UTEST block (0x00400000 - 0x00403FFF) in flash memory through JTAG probe which is not supposed to be erased by RappID Bootloader.

Hello,

Indeed RappID Bootloader erases entire program flash memory.

If you program Dflash/Utest flash block via JTAG these blocks are NOT erased by the RappID bootlader.

Hope it helps.
