Part Number: TDA4VM
Dear TI Team,
I am trying to boot the J21E-EVM board with eMMC but the eMMC is not working.
Steps that were done are as follows. [Assuming the EVM is at the U-BOOT prompt]
1. setenv serverip 10.0.0.1
2.setenv ipaddr 10.0.0.2
3.setenv gatewayip 10.0.0.1
4.setenv netmask 255.255.255.0
5.Once the server is alive issue tftp 0x80080000 ifs-j721e-evm.raw
6.mmc write 0x80080000 0x0 0x7af288 ----> This is getting failed.as we are giving the whole ifs-j721e-evm.raw's size
7. Since 6 th step is failing, we have splitted the image into 1k blocks and wrote into eMMC. then it started writing to eMMC as follows.
mmc write 0x80080000 0x0 0xf4240
and so on till
mmc write 0x80080000 0x895440 0xf4240
8. mmc read 0x80080000 0x0 0x7af288
MMC read: dev # 0, block # 0, count 8057480 ... "Synchro
The EVM is getting struck here. So kindly give us your thoughts on this for the following questions
1. Why eMMC write is failing in 6th step, Is it due to size issue? if size is the issue, then what could be the sizes that are allowed or minimum/maximum sizes.
2. After writing 1k blocks the eMMC write is successful but why the eMMC read is not successful. (8 th step)?
Thank you,
Regards,
Krishna
