Part Number: CC2340R2

Tool/software:

1:I want to used ROM Serial Bootloader Commands to program the chip's flash. Can you give me some Reference code？

2：How to calculate the CRC of this place when I execute BLDR_CMD_DOWNLOAD_CRC? Can you give me the calculation formula and initial value？

3：I want to know how to execute a BLDR_CMD_CRC32 command. Can you provide me with an example of a data stream?

Hello,

I would recommend referencing the following code: https://github.com/TexasInstruments/ble_examples/tree/simplelink_low_power_f3_sdk-7.40/tools/TI_CC2340_Linux_SBL

I hope this will help,

Best regards,

Can you check the ccfg.bootCfg.crc32 is set on 0X0C-0X0F?

In bsp say this:

/*CCFG File Regions:
ccfg.bootCfg.crc32 0x0000-0x000B
ccfg.crc32 0x0010-0x074B
ccfg.userRecord.crc32 0x0750-0x07FB*/

uint8_t Crc32Value[4];
uint16_t CcfgRegionStart[4] = {0x0000, 0x0010,0x075,0x07D0};
uint16_t CcfgRegionEnd[4]= {0x000B, 0x0074,0x0CB,0x07FB};
uint16_t regionStartAddr;

fseek(CCFGfPtr,regionEndAddr,SEEK_SET);
/*Add data to region End*/
fwrite(&Crc32Value[0],1,4,CCFGfPtr);

But this regionEndAddr =0x0B! Why the crc set to 0XB-0X0E???
