here is the implementation of the functions:
# function ota_conv_sizes # Convert a bytes size to a block size # input bytesize : size in bytes to convert # input blksize : size of a block in bytes # output num_blk : converted size in blocks setenv ota_conv_sizes 'setexpr num_blk $bytesize / $blksize ; setexpr mod_blk $bytesize % $blksize ; if itest $mod_blk > 0 ; then setexpr num_blk $num_blk + 1; fi;'
# function ota_mmc_write # Write a memory buffer to mmc drive # input floadaddr : address of buffer to write # input u_part_start : block start in mmc # input num_blk : number of block to write setenv ota_mmc_write 'if itest $ota_verbose == 1 ; then echo "mmc write ${floadaddr} ${u_part_start} ${num_blk};"; fi; mmc write $floadaddr $u_part_start $num_blk; ret=$?; if itest $ret != 0 ; then setenv ota_abort_reason "mmc write ${floadaddr} ${u_part_start} ${num_blk} failed"; setenv ota_abort 1; fi;'
the old u-boot version supported 'part info mmc 0:${u_part_num} u_part_start u_part_sz u_part_blksz;' to get the block size.
Old upstream U-Boot?
